CHAPTER 1
DESCRIPTION
STCMAC is a macro source program which is used to build STCMAC.UNV,
STCUNV.UNV, and TYPER.REL. These contain definitions for commonly used
macros which are intended to make life easier for the MACRO-10 hacker.
These universal files (and .REL file) differ only in content. STCMAC
contains all macro definitions, STCUNV contains a subset of the macros
contained in STCMAC which does not include the "$TYPER" macro.
TYPER.REL contains a stand-alone expansion of the $TYPER macro.

Any comments concerning STCMAC should be directed to Rex Shadrick
at the above address.
CHAPTER 2
STC SPECIFIC SYMBOL DEFINITIONS
STCMAC contains some symbol definitions that are of importance only
to programs written for STC. These symbols are definitions for STC
privilege bits (used in the JBTPRV monitor table), local FACT.SYS entry
definitions, and two local CALLI UUOs (USRNM. and USRLG.). These
definitions are of little or no importance to anyone outside of STC and
can be ignored.
CHAPTER 3
VERSION/TITLE MACROS
There are two macros which manipulate version numbers. They are:
"$VRSN" and "$TITLE". Note that these macros define symbols which are
required by other STCMAC macros and routines.
3.1 THE $VRSN MACRO
This macro is used to define the program's version number in
TOPS-10 compatible format. It requires two arguments: a three letter
abbreviation of the program name (preferably the program's CCL name),
and the version number in the format that is typed by DIRECT. Example:
$VRSN STC,1(60)-2
This defines six symbols of importance to the programmer. These
are: xxxVER, xxxMIN, xxxEDT, xxxWHO, xxx.VN, and TP.PFX, where "xxx" is
the CCL name given as the first argument. xxxVER is the major version
number, xxxMIN is the minor version number, xxxEDT is the edit level,
xxxWHO is the programmer (0-7), xxx.VN is a 36 bit version number which
is the combined form of the previous four numbers (note that this symbol
is generated using the "VRSN." macro from MACTEN.UNV) and TP.PFX is an
18 bit quantity which is the SIXBIT CCL name.
3.2 THE $TITLE MACRO
This macro is used in conjunction with the $VRSN macro to generate
a "TITLE" pseudo-op, with the program's version number appended to the
text of the title statement. This macro takes five arguments: a text
string which is the main body of the title statement, the program's CCL
name (the same as the one given to the $VRSN macro), an optional
pseudo-op to be used instead of "TITLE" (e.g. "UNIVERSAL" to generate a
universal file), a number to specify which pass to execute the macro
(more of this later), and another text string which will be appended to
the line following the version number that is generated.
VERSION/TITLE MACROS Page 3-2
THE $TITLE MACRO
This macro can be used to construct virtually any type of statement
the programmer would want that contains the program's version number in
text format, but is normally used to generate a TITLE/UNIVERSAL
pseudo-op. Some examples of the use of $TITLE are:
$TITLE STCUNV - STC Common Macro Definitions,STC,UNIVERSAL
Would generate:
UNIVERSAL STCUNV - STC Common Macro Definitions %1(60)-2
$TITLE <\EBUTIL >,EBU,SIXBIT,3,<\>
Would generate:
SIXBIT \EBUTIL %1(1)-4\
$TITLE <[Assembling STCUNV Version>,STC,PRINTX,1,<, pass 1]>
$TITLE <[Assembling STCUNV Version>,STC,PRINTX,2,<, pass 2]>
Would generate:
IF1,< PRINTX [Assembling STCUNV Version %1(60)-2, pass 1]
>
IF2,< PRINTX [Assembling STCUNV Version %1(60)-2, pass 2]
>
The pass number argument to $TITLE is a two bit number which
instructs $TITLE which passes to assemble this macro on. This value is
assumed to be 3 if zero, blank or omitted. An argument of 1 will direct
it to assemble only during pass 1, 2 for pass 2 or 3 for both passes.
3.2.1 The $PASS Macro
The last two examples are contained in a single special-case macro
called "$PASS". This is a single macro whose main function is to type
on the user's console what it is that (s)he is assembling. The two
arguments passed to this macro are the program's name and the CCL prefix
(as given in the $TITLE macro).
An example of its use:
$PASS STCUNV,STC
Would generate the last two $TITLE macros given above.
CHAPTER 4
RELOCATION MACROS
There are several macros defined which are used to control program
relocation, phase, and literal/variable pool. These macros are:
$RELOC, $ABS, $END, $HIGH, $LIT, $LOW, $PRGEND and $VAR.
4.1 THE $RELOC MACRO
This macro is invoked a maximum of once per program and should be
used before any other relocation macros are called. There are three
optional arguments: the first specifies whether one or two segment code
is to be generated, the second determines whether literals are to be
dumped when the segment changes and the third is the high segment base
relocation address. The first argument is either "ONE" for single
segment (low segment only) code or "TWO" for two segment code (high and
low segments). The second argument is either "LIT" to dump literals
when the segment changes (via $HIGH or $LOW) or "NOLIT" to suppress
dumping of literals. When "LIT" is set, the literal pool will be dumped
in the current segment before the segment is changed. The defaults for
the arguments are "TWO,NOLIT,400000". An example of its use:
$RELOC TWO,LIT
4.2 THE $ABS MACRO
This macro is used to generate absolute assembly code (i.e. "LOC"
pseudo-op). Its single argument is the address to begin assembly.
Example:
$ABS 137
RELOCATION MACROS Page 4-2
THE $END MACRO
4.3 THE $END MACRO
This macro will dump the literal pool (in the high segment) and
variable pool (in the low segment) and generate an "END" statement. The
single optional argument is the start address of the program as in the
"END" pseudo-op. Example:
$END START
4.4 THE $HIGH MACRO
This macro will reset the relocation to high segment code. This
macro should only be used if two segments were specified to the $RELOC
macro. If the "LIT" option was specified to $RELOC, then the literal
pool will be dumped before changing segments. Example:
$HIGH
4.5 THE $LIT MACRO
This macro will set the relocation to the high segment, then dump
the literal pool. Example:
$LIT
4.6 THE $LOW MACRO
This will set the program relocation to the low segment. If "LIT"
was given in the $RELOC call, the literals will be dumped in the current
segment before changing to the low segment. Example:
$LOW
4.7 THE $PRGEND MACRO
This macro will dump the literal and variable pools (as in the $END
macro), then generate a PRGEND pseudo-op, optionally with the program
start address. Example:
$PRGEND
RELOCATION MACROS Page 4-3
THE $VAR MACRO
4.8 THE $VAR MACRO
This sets the program relocation to the low segment and dumps the
variable pool. Example:
$VAR
CHAPTER 5
STACK MACROS
STCMAC contains macros which allocate frames or local variables on
the software stack. These routines require that the stack pointer is in
register 17, defined as "P", and will also save register 16 and use it
for a frame pointer during the context of the variables/frame.
5.1 THE $VARIABLE MACRO
This macro is used to stack registers 1 through 16 and allocate
local variables on the stack. This macro generates a call to the
routine with the entry point ".FRAME", which will use register 16 for a
frame pointer.
The format of the call is:
$VARIABLE (call variable,register variable,<variable list>)
The "call variable" is a stack variable which will point to the
address of the return address on the stack, the "register variable" is a
stack variable which points to the address on the stack where registers
1 thru 16 are saved and "variable list" is a list of variable names to
be generated. These variables are macro definitions which implicitly
index register 16, so instructions using these symbols cannot use
indexing. On the next "POPJ P,", these variables are deallocated and
all saved registers are restored. The format of the variable list is a
list of symbol names for unit length variables. For multiple word
variables, the format of the variable name is of the form: "<VAR,4>"
which would generate four words of storage for the symbol "VAR". On
return from the macro, register "T1" will point to the argument block.
Note that the generated storage is NOT pre-zeroed.
STACK MACROS Page 5-2
THE $FRAME MACRO
5.2 THE $FRAME MACRO
This macro generates the subroutine which is called by the
$VARIABLE macro. This macro is expanded in the expansion of the $TYPER
macro. The generated code is a subroutine which has a global entry
called ".FRAME" and will call the routines generated by the "$LOCAT" and
"$PARAM" macros. There is a single optional argument to this macro
which is the CPU type (PDP6, KA10, KI10 or KL10), which if omitted will
default to the CPU type that it is being expanded on. This will produce
adjust stack pointer (ADJSP) instructions if running on a KL10 or later
CPU.
5.3 THE $LOCAT MACRO
This macro expands to a routine which calculates an effective
address. The reason there is a subroutine to do this rather than
relying on the hardware is the case where the address is a register that
has been saved on the stack, this routine will properly point to the
location on the stack where the register has been saved. This assumes
that register 16 points to a frame on the stack which contains the
registers, as setup by the $VARIABLE macro and .FRAME subroutine.
The routine generated has a global entry point of ".LOCAT", expects
the address to be calculated in T1, will return the effective address in
T1 and destorys T2. This macro is expanded by the "$TYPER" macro.
5.4 THE $PARAM MACRO
The $PARAM macro generates a routine to find the address of the
instruction which called the current routine. This routine is used by
.FRAME, and assumes the calling instruction to be an XCT or PUSHJ P,@.
This routine properly detects DDT breakpoints. The entry point to this
routine is ".PARAM", and is contained in TYPER.REL along with .FRAME and
.LOCAT.
CHAPTER 6
TYPER MACROS
The TYPER macros are a set of macro definitions and subroutines
which are designed to make ASCII output easier for the programmer, thus
leaving him more time for more esoteric programming. They are primarily
used for TTY output, however they may also be used to do output to any
device or file. These macros depend on symbols that are generated by
the $VRSN and $RELOC macros.
NOTE
The code generated by the $TYPE and
$TYPES macros is one location of inline
code which is a PUSHJ P, indirect or XCT.
All $TYPE and $TYPES calls can therefore
be SKIPped around.
6.1 THE $NUMBER MACRO
The $NUMBER macro is used to generate a descriptor word for the
$NUM output type call (used by the $TYPE macro). This macro creates a
single word which describes the location for the number to be output,
and the format in which it is to be typed. The call is:
$NUMBER ($ADR,$TYP,$WID,$DEC,$NOT)
Where "$ADR" is the address of the data to be output, "$TYP" is the
output type; one of "DOUBLE", "SINGLE" or "UNSIGNED" (default), which
selects double/single precision or unsigned output. "$WID" is the width
of the integer portion of the number (0 is default), "$DEC" is the
number of digits to be typed to the right of the decimal point for
single/double precision or the output radix for unsigned (5 is the
default for single/double, 8 for unsigned). "$NOT" is the notation for
output; for single/double: "REGULAR" for regular floating point output
or "SCIENTIFIC" for scientific type output, for unsigned output:
TYPER MACROS Page 6-2
THE $NUMBER MACRO
"BLANK" for blank fill on leading zeroes or "ZERO" for zero fill on
leading zeroes. "REGULAR" or "ZERO" is the default for this field if
not specified.
6.2 THE $TYPE MACRO
The $TYPE macro is the macro which is used to output an ASCII
string with output conversions for outputting numbers, ASCII or SIXBIT
substrings, etc. The arguments to the macro call describe the type of
message (error, warning, information, or operator intervention
required), the message prefix, and the type of output conversion to be
used for the supplied arguments at runtime. The format of the call is:
$TYPE ($HDR,$SFX,$SUB,$TXT,$TRL,$RET,$ORN)
Where "$HDR" is the message type,"$SFX" is the last three
characters of the message prefix, "$SUB" is the substitution type,
"$TXT" is the ASCII text, "$TRL" is the trailer code (i.e. <CR><LF> or
no <CR><LF>), "$RET" is the address to return to and "$ORN" is the
output routine to be used. These are described in detail below:
6.2.1 $HDR
This argument specifies the header type to be used. The header
types available are:
Option Leading Description
Type Char
F ? For a fatal error.
I [ For an information message.
M " For an operator information message.
N For no header or prefix.
O $ For operator intervention required.
T <TAB> For a leading tab with no prefix.
W % For a warning message.
A six character message prefix consisting of the program's CCL name
(as defined for the $VRSN macro) and a three character abbreviation
(supplied as the "$SFX" argument) will be output for header types F, I,
M, O and W, followed by a <TAB> character (Control-I) will be output at
the beginning of the message. If the header type is I, a "]" will be
output at the end of the line, unless the "N" option is given as the
argument "$TRL", in which case the "]" will be deferred until then next
$TYPE call which ends the line without specifying that the trailer be
omitted.
TYPER MACROS Page 6-3
THE $TYPE MACRO
6.2.2 "$SFX"
This argument is a three character suffix which is appended to the
program's CCL name to be output as part of the message prefix. An error
message will be issued if this argument is non-blank when used with
header type "T". If the suffix is non-blank when used with the header
type "N", the code generated will be an XCT instruction of the $TYPE
call which uses the same suffix with a header type of F, I, M, O or W.
The $TYPE macro will generate a label of the form "$$$sfx" (where "sfx"
is this argument), which implies that there can be only one call which
uses this suffix with any header type other than "N".
6.2.3 "$SUB"
This argument specifies the substitution type to be performed on
the argument passed in accumulator "T1". This substitution is performed
on the first occurrence of a "|" (vertical bar) character which is
encountered in the supplied ASCII string. These substitutions are:
6.2.3.1 $NON -
No substitution is to be performed.
6.2.3.2 $ASC -
The ASCIZ string pointed to by T1 is output.
6.2.3.3 $BIT -
T1 contains the address of the following argument block. This
will type an ASCIZ string which corresponds to the non-zero bit in
the bit mask given. Examples of this substitution type are given
later.
c(T1)+0/ Flags and the address of the message table.
c(T1)+1/ The bits to be tested.
c(T1)+2/ The bit mask to be ANDed.
c(T1)+3/ Pointers to user message separators.
TYPER MACROS Page 6-4
THE $TYPE MACRO
The flags in the first word are:
TF.AND Output "and" before the final message string.
TF.OR Output "or" before the final message string.
TF.FLD Output field values.
TF.LIN Separate the message strings with <CR><LF>.
TF.USR Separate the messages with the strings supplied in the
fourth word.
TF.SIX The message strings are in SIXBIT.
TF.BIT The second word is an indirect pointer.
TF.MSK The third word is an indirect pointer.
This will take the bit word (the second argument word or the
word pointed to by the second argument word if TF.BIT is set), AND
it against the bit mask (third argument word or the word pointed to
by the third argument word if TF.MSK is set), then scan the bits
from the most significant bit to the least significant bit. If one
of these bits is found to be on (a "1"), then the corresponding
message from the message table (pointed to by the right half of the
first argument word) will be output. The string to be used to
separate the message strings if more than one bit is set is a comma
(",") unless a user separator string is given if TF.USR is set.
Then it is the string pointed to by the left half of the fourth
argument word. Otherwise the separator is <CR><LF> if TF.LIN is
set. The final two message strings are separated by "and" if
TF.AND is set, "or" if TF.OR is set or the string pointed to by the
right half of the third argument word if TF.USR is set. If TF.FLD
is set, then the bit mask is used to extract a value to be used as
an index into the message table to output a single message.
This substitution type is useful for outputting error messages
in which the program is given a bit mask of what errors occured (as
in the case of the device status bits on an I/O error). For the
case of having an error number (like a LOOKUP/ENTER error), the
TF.FLD option can be used.
6.2.3.4 $BLK -
This format will type the number in T1 in decimal unless it is
an integral multiple of 128, in which case it will type the number
divided by 128, followed by a "B" (for "blocks"). This
substitution type is used to output file sizes.
6.2.3.5 $CHR -
This will type the contents of T1 as a single right justified
ASCII character.
TYPER MACROS Page 6-5
THE $TYPE MACRO
6.2.3.6 $COR -
This is used to type a core size passed in T1. If the number
is an integral multiple of 512 (1024 if running on a KA-10 or
PDP-6), the number will be divided by 512 (or 1024) and typed with
a "P" ("K" for KA-10 or PDP-6) appended. Otherwise, the number is
typed in decimal.
6.2.3.7 $DAT -
This will type the contents of T1 as dd-mmm-yy, where "dd" is
the day of the month, "mmm" is the three letter abbreviation of the
month, and "yy" is the year.
If the argument in T1 is minus 1, then the current date is
typed, else it is assumed to be in DEC 15 bit date format
(((year-1964)*12+month-1)*31+day-1).
6.2.3.8 $DAY -
This will print a day of the week. If the contents of T1 is
minus one, then the current day will be printed, otherwise the
argument is assumed to be in universal date/time format.
6.2.3.9 $DEC -
This will type the contents of T1 in decimal.
6.2.3.10 $DTL -
This will type a date in "long" format (e.g. September 30,
1978). If the argument in T1 is negative, then the current date is
printed, if the left half of T1 is positive and non-zero, then it
is assumed to be a universal date/time, if the left half is zero,
then it will processed as a 15 bit date.
6.2.3.11 $ENT -
This will type the OPEN and LOOKUP/ENTER blocks as pointed to
by T1. The left half of T1 contains the address of the open block,
the right half contains the address of the LOOKUP/ENTER block.
This will type the file name in the format:
"dev:file.ext[P,Pn,sfd1, ...]".
TYPER MACROS Page 6-6
THE $TYPE MACRO
6.2.3.12 $FUL -
This assumes that the contents of T1 is six SIXBIT characters,
and will type them converted to ASCII including trailing spaces.
6.2.3.13 $FUN -
If T1 is negative and bits 1 thru 12 are zero, this will type
the ASCIZ string pointed to by T1, otherwise it will type T1 as a
right justified ASCII character, In both cases, control characters
are typed as "^X", and lower case characters are typed as "'X".
6.2.3.14 $HEX -
The contents of T1 are typed out as a hexadecimal integer.
6.2.3.15 $LFT -
The contents of the left half of T1 are typed (assumed to be
three or less SIXBIT characters). Trailing spaces are deleted.
6.2.3.16 $LIN -
This will type a carriage-return/line-feed sequence. No
argument is required.
6.2.3.17 $LKP -
This substitution type is identical to the "$ENT"
substitution.
6.2.3.18 $NAM -
This substitution type is used to output a user name up to
twelve characters in length. On entry, T1 contains the address of
the first of the two SIXBIT words. Trailing spaces are deleted.
TYPER MACROS Page 6-7
THE $TYPE MACRO
6.2.3.19 $NUM -
This types a number in a according to a format defined by the
user. The contents of T1 contain the word generated by the $NUMBER
macro, which describes the format for the number to be typed.
6.2.3.20 $OCT -
Will output the contents of T1 in octal.
6.2.3.21 $PFX -
Will type the program's CCL name followed by the contents of
T1. If T1 is positive it is typed as an ASCII character right
justified, if negative, as a SIXBIT string.
6.2.3.22 $PPN -
Types the contents of T1 in "PPn" format, i.e. [P,Pn].
6.2.3.23 $PRO -
Types the contents of T1 as a three digit octal number with
leading zeros, enclosed in angle brackets (<nnn>), as a file
protection code.
6.2.3.24 $PTH -
Types the path block pointed to by T1 as [P,Pn,sfd1, ...].
6.2.3.25 $R50 -
Types the contents of T1 as six RADIX-50 characters, trailing
spaces deleted.
TYPER MACROS Page 6-8
THE $TYPE MACRO
6.2.3.26 $RUN -
Types the contents of T1 as program runtime, if bit 0 is zero
then T1 is assumed to be in milliseconds, otherwise in jiffies.
The format in which it is typed out depends upon the width of the
field given in the $TYPES JST call. If the width is negative, then
the null fields of the output (i.e. hours and minutes) are space
filled), if zero they are suppressed, if positive, all fields are
output.
6.2.3.27 $SCN -
Will type a SCAN compatible file specification block which is
pointed to by T1. The file name is printed as
"dev:file.exe[P,Pn,sfd1, ...]" with any wildcards output in the
appropriate places (e.g. "DSKA:A?????.*[?,?]").
6.2.3.28 $SIX -
Will type the contents of T1 as up to six SIXBIT characters
with trailing spaces deleted.
6.2.3.29 $SPC -
Types a string of spaces. T1 contains the number of spaces to
be output.
6.2.3.30 $SUB -
Types the string pointed to by T1 as an ASCII string, but with
substitutions, similar to the "$TXT" argument to the $TYPE call.
6.2.3.31 $TIM -
Types the contents of T1 as a time of day in the form
"hh:mm:ss", where T1 contains the number of milliseconds since
midnight or minus one for the current time.
TYPER MACROS Page 6-9
THE $TYPE MACRO
6.2.3.32 $TML -
This types a time of day in the format hh:mm {a.m.|p.m.},
where the argument is either milliseconds since midnight, or minus
one for the current time.
6.2.3.33 $UNV -
Types a date/time in the format: dd-mmm-yy:hh:mm:ss. The
contents of T1 are assumed to contain a date/time in universal
date/time format.
6.2.3.34 $VER -
Types the contents of T1 in version number format (i.e.
12D(123)-4).
6.2.3.35 $XWD -
Similar to $PPN except that the square brackets ("[]") are not
typed.
6.2.3.36 $UR1 Thru $UR7 -
Uses a user supplied output conversion routine as given in the
"$TYPES RTN" call.
6.2.3.37 $IND -
This performs no immediate substitution or conversion, but is
used to give multiple substitution types in a single $TYPE call.
This specifies to .TYPER that the contents of T1 contains in the
left half the negative number of arguments supplied, in the right
half the address of the table of words each containing the
substitution type and address of the argument (the address may
contain indirect bits and indexing). Each word is used
successively to control a substitution as a "|" character is
encountered in the text string.
If no argument is given as the substitution type, $NON is assumed
to be the default.
TYPER MACROS Page 6-10
THE $TYPE MACRO
6.2.4 "$TXT"
This argument is the ASCII string to be output. Any "|" characters
found in the string will flag a substitution to be performed and call
the indicated conversion routine.
6.2.5 "$TRL"
This specifies the trailing string to be appended to the text. It
may be one of: "N" for no trailer, or "C" for a
carriage-return/line-feed sequence. In the case of "C", if the message
type was information ("I"), then the "]" will be inserted before the
<CR><LF> sequence. If this argument is left blank, "C" is assumed.
6.2.6 "$RET"
This specifies the address to return to on completion of the $TYPE
call. If left blank, "N" is assumed, which will return to the next
instruction following the call. The returns are:
Return Description
C Return to the monitor and allow a CONTINUE.
E Return to the monitor and reset all I/O.
M Return without resetting I/O, but don't allow
a CONTINUE.
N Return to the next instruction.
N1 Return to the next instruction plus 1.
P Perform a return in behalf of the caller
(similar to calling with "PJRST").
P1 Similar to "P", but skip returns.
S Calls .FMSGE in SCAN following the message,
for fatal error processing.
If there is a return code given, but does not match any of the
above, then it is assumed to be an address, and will be transfered to
upon completion.
6.2.7 "$ORN"
This is the output routine to be used by .TYPER. If left blank,
then the default output routine as set by the last $TYPES OUT call is
used. If the output routine is set to zero, then .TYPER's default
output routine is used.
TYPER MACROS Page 6-11
THE $TYPE MACRO
Some examples of the $TYPE call are:
$TYPE (N,,$NON,<This is a message.>)
$TYPE (I,MSG,$NON,<This is an information message>)
Would type:
This is a message.
[PFXMSG This is an information message]
Some substitutions:
MOVEI T1,[SIXBIT \USER NAME\]
$TYPE (I,USR,$NAM,<The user name is |>)
Produces:
[PFXUSR The user name is USER NAME]
MOVE T1,.MYPPN##
$TYPE (W,PPN,$PPN,<The PPn is |>)
Produces:
%PFXPPN The PPn is [1,2]
DATE T2,
MOVE T1,[-3,,[$DAY [-1]
$TML [-1]
$DTL T2]]
$TYPE (M,DAY,$IND,<Today is |, | |>)
Produces something like:
"PFXDAY Today is Monday, September 25, 1978 08:30 a.m.
An example of the $BIT substitution:
OUT DSK,
POPJ P,
GETSTS DSK,T2
MOVEI T1,[TF.AND!TF.BIT+MSGTAB
T2
IO.ERR]
$TYPE (F,ODE,$BIT,<Output DSK error, status = |>,,P)
MSGTAB: [ASCIZ \Improper mode\]
[ASCIZ \Hard device error\]
[ASCIZ \Hard data error\]
[ASCIZ \Block too large\]
Would print something like:
?PFXODE Output DSK error, status = Improper mode and Hard data error
TYPER MACROS Page 6-12
THE $TYPER MACRO
6.3 THE $TYPER MACRO
The $TYPER macro when called, will generate the code needed to
process $TYPE and $TYPES macro calls. This macro exists in STCMAC.UNV
but not in STCUNV.UNV. TYPER.REL is a standalone expansion of this
macro. For programs which use SCAN, STCUNV.UNV should be searched since
it will use much less core at assembly time, and the program should be
loaded with TYPER.REL. The expansion of this macro also includes the
expansion of the $FRAME, $PARAM and $LOCAT macros. The format of the
$TYPER macro call is:
$TYPER ($LST,$SCN,$SEG,$CPU)
Where "$LST" is either "LIST" or "NOLIST" depending on whether or
not the programmer wants the expanded code in the program listing,
"$SCN" is either "SCAN" or "NOSCAN" to specify whether or not SCAN will
be loaded with this program, "$SEG" is "ONE" or "TWO" to specify the
number of segments of code to be generated and "$CPU" is the CPU type to
generate code for. The defaults are:
$TYPER (LIST,SCAN,TWO)
Where the cpu type defaults to the type on which the assembly is
taking place.
6.4 THE $TYPES MACRO
The $TYPES macro is used in conjunction with the $TYPE macro to
control output destination, time stamping, etc. There is a single
argument to this macro, the format of the call is:
$TYPES fnc
Where "fnc" is one of the following:
6.4.1 BUG
This option implies that a fatal program error has been
detected. This will cause an error message to be typed, then the
program will exit.
TYPER MACROS Page 6-13
THE $TYPES MACRO
6.4.2 COL
Will return in AC T1 the current horizontal position in the
output line. This column counter is valid only when time stamping
and/or justification are being used.
6.4.3 DMP
Will force the text buffer to be dumped if the standard output
routine is being used. This routine normally buffers in core the
entire line to be output, then outputs it all at once when end of
line is encountered. This call will force the partial line to be
output.
6.4.4 ERR
This will cause all fatal error messages (i.e., all with the
header type "F") to increment .JBERR. This is used as a flag to
other programs that a system program error has occured.
6.4.5 INI
This call should be performed before any other $TYPE or $TYPES
calls. This will initialize TYPER, and setup the program's CCL
name and initial output routine. On entry, .TYPES assumes that the
CCL name is in SIXBIT in the left half of T1, the initial output
routine in the right half of T1. If the output routine is left
zero, the standard output routine will be used. A sample call is:
MOVSI T1,TP.PFX
$TYPES INI
6.4.6 JST
This is used to setup software tab stops in the output line.
On entry, T1 contains in the left half the negative number of tab
stops, in the right half the address of the table of tab stops
formatted "XWD width,column". The tab stop table must be in
ascending order. For a tab stop with a non-zero width, if a $BLK,
$COR, $DEC, $HEX, $NUM, $OCT, $RUN or $XWD substitution is used,
the number will be output right justified in the field, with
leading space fill.
TYPER MACROS Page 6-14
THE $TYPES MACRO
6.4.7 LOC
This routine is used to obtain the contents of a memory
location. It is assumed that the calling routine has issued a
"$VARIA" macro call prior to calling this function. On entry, T1
contains an address (indexing and indirect may be used), on return
T1 will contain the contents of that location.
6.4.8 OUT
Takes the address of an output routine in T1. This will
change the default output routine to be used. On return, T1
contains the address of the previous output routine. The output
routine specified will be given the character to be output in the
right half of T1. The left half of T1 will contain a -1 if the
character is part of a time stamp, -2 if it is part of a time stamp
label or zero if none of the above. The output routine may not
destroy any AC.
6.4.9 PRM
This call will clear a possible Control-O, then output a
prompt on the user console. On entry, T1 should contain (right
justified) ">" for a standard prompt, "!" for a running prompt, "/"
for a paused prompt or "#" for a continuation line on any of the
above. The prompt output is of the form "ccl> ", where "ccl" is
the program's CCL name as given in the $TYPES INI call, and the
character following is the character passed in T1 on entry. This
routine does an implied $TYPES DMP to insure that the prompt gets
output.
6.4.10 RTN
This call is used to identify user defined output routines to
be used with the "$UR1" thru "$UR7" substitution types for the
$TYPE call. T1 should contain in the left half the number of
routines given, and the address of the table of the routines in the
right half. The first routine in the table is assigned to $UR1,
the second to $UR2, etc. These output routines will be given the
argument it T1 on entry and may destroy T1, T2, T3 and T4. Note
that while in the context of these routines, the user AC's 1 thru
16 have been pushed on the stack, and AC 16 contains a frame
pointer.
TYPER MACROS Page 6-15
THE $TYPES MACRO
6.4.11 RST
This call will restore the status of TYPER as saved by $TYPES
SAV.
6.4.12 SAV
This call will save the status of the type routines so that a
$TYPE or $TYPES call will work if executed during a software
interrupt which occurs while executing inside TYPER. This can be
called to save the status only one level deep.
6.4.13 SYS
This call will change the system prefix (the program's CCL
name). On entry T1 should contain the new prefix in the left half
(in SIXBIT).
6.4.14 TIM
This will instruct TYPER to precede all output produced by
$TYPE calls with a time stamp. The time stamp is of the form
"hh:mm:ss msg<TAB>", which is the time of the day, and "msg" is an
optional SIXBIT label which is some kind of message abbreviation
(like the "USER" and "MONTR" labels in a batch log file). On entry
T1 contains a -1 if normal time stamps, zero to turn off time
stamps or -1 in the left half and the address of a location (in the
right half) which contains a SIXBIT label to be output following
the stamp. In all cases, on return T1 contains the previous time
stamp argument.
CHAPTER 7
THE ERROR MESSAGE MACRO
$PRINT is a macro to produce assembly time error messages via
PRINTX pseudo-ops. The format and use of the macro is similar to that
of $TYPE except that there is no substitution performed, or alternate
return addresses or output routines (for nearly obvious reasons). The
format of the call is:
$PRINT ($HDR,$PFX,$TXT)
Where $HDR is one of F, I, O, W (which do roughly the same things
as in the $TYPE call), $PFX is a three character string to be appended
to the CCL name (TP.PFX) for a message prefix, and $TXT is the text to
be output. This macro generates no code, and is only of value at
assembly time.
CHAPTER 8
PUTTING IT ALL TOGETHER
This chapter deals with how to use all of what has been explained
in the previous sections. Using these macros is very simple after the
programmer has gotten some experience with them, however they may look a
bit complicated at first. This will attempt to make some of the
interactions between the macros a little bit more clear.
The most probable reason anybody would want to use any of these
macros is to take an advantage of the $TYPE macro to type his/her
error/warning messages. A good rule of thumb to keep in mind is that
since this macro references symbols produced by most of the other
macros, it is generally a good idea to use all of them ($VRSN, $TITLE,
$RELOC, etc.). If the program uses SCAN, it is advisable to use the
TYPER.REL module, which contains the processors for the $TYPE, $TYPES
and $VARIA macros. In doing this, the program being created can search
STCUNV.UNV instead of STCMAC.UNV, which will save about 20 pages of core
at assembly time. If the program does not use scan and/or has
non-standard AC definitions, the $TYPER macro must be expanded within
the program, which implies searching STCMAC.UNV.
The following sections deal with the specifics of how to properly
setup and use everything.
NOTE
The STCMAC macros use a special macro
definition format defined in STC's local
version of MACRO-10. This is the macro
expansion format (SALL, LALL and XALL)
enclosed in square brackets preceding the
argument list. If this version of MACRO
is not being used to assemble the
programs, then a "/P" switch should be
given to macro during assembly to avoid
overflowing the assembler's push-down
stack.
PUTTING IT ALL TOGETHER Page 8-2
INITIALIZING EVERYTHING
8.1 INITIALIZING EVERYTHING
Before any of the heavy macros can be used, things should be
properly initialized. This consists of defining a version number,
generating the title using the $TITLE macro if we want pretty titles and
initializing the relocation macros. It is strongly recommended that the
program also search MACTEN and UUOSYM.
The first page of a program could look something like:

$ABS 136 ;Set to customer version word

EXE.VN ;Both places just for fun
$TITLE EXEUTL -- Utility for Tweaking EXE Files,EXE
$PASS EXEUTL,EXE
8.2 AC DEFINITIONS
Some of the macros (like $TYPER) require specific definitions for
some AC names. Generally, using SCAN compatible definitions (AC's 1
thru 4 named T1 thru T4, AC's 5 thru 10 named P1 thru P4 and P = 17)
will work. The main requirement is that the stack pointer is in
register 17 with the name "P" and that there are AC definitions for T1
thru T4 and P1 thru P4. Other combinations are possible, but mostly
untested. If the $TYPER macro encounters some kind of inconsistency in
the definitions while being expanded, it will issue an error message
(using the $PRINT macro) to warn the programmer.
PUTTING IT ALL TOGETHER Page 8-3
RUNTIME INITIALIZATION OF THE TYPER ROUTINES
8.3 RUNTIME INITIALIZATION OF THE TYPER ROUTINES
Before any $TYPE or $TYPES calls can be executed by the user
program, the $TYPES INI call should be issued. This will properly
initialize the TYPER routines so that everything will function normally.
If using SCAN, the best place to put this call is fairly soon after the
.ISCAN call.
An example of the initialization is:
MOVE T1,ISCNPT ;Get the ISCAN pointer
PUSHJ P,.ISCAN## ;Go initialize SCAN
MOVSI T1,TP.PFX ;Get system prefix
$TYPES INI ;Initialize TYPER
Note that the symbol "TP.PFX" is defined by the $VRSN macro.
After this initialization, the programmer is free to use any of the
$TYPE and $TYPES calls.
8.4 SOME HINTS ON USING STCMAC
There are some useful things associated with these macros, which
may not justify using STCMAC to begin with, but nice to have anyway.
8.4.1 $TYPES BUG
This macro is used where the programmer has detected a fatal
program bug, i.e. some section of code that (s)he thinks is impossible
or improbable to get to, or anything that (s)he does not know how to
handle. This macro can be used in the place of a HALT instruction or
something equally gross. This macro generates one line of inline code
(as does $TYPE), and will produce an error message which informs the
user that a program logic error has occurred and will give the absolute
and relative (to the module) PC of the error.
8.4.2 $VARIA, .LOCAT And .PARAM
These are useful for subroutine entry and parameter fetching. The
$VARIA macro is used on entry to the subroutine to stack AC's 1 thru 16,
and allocate any required local storage. On return, T1 will contain a
pointer to the argument list (assuming that the subroutine was called
with a PUSHJ P,@[addr ....). Any addresses passed as arguments
(including saved AC's) can be located using the .LOCAT routine. An
example of how this can be done is shown in appendix A.
PUTTING IT ALL TOGETHER Page 8-4
SOME HINTS ON USING STCMAC
8.4.3 The $PRINT Macro
This macro is useful for outputting assembly time error messages or
information.
8.4.4 $TYPES OUT
By changing the default output routine via this call, the
programmer can direct his output to virtually anything (s)he wants. It
can be used to output to a file, build a string in core, etc. Having
done so, the programmer then has full access to the $TYPE macro and all
associated routines to do formatted output to a file (or any other
destination (s)he has in mind). The $TYPE macro has a fairly high per
character overhead, but for limited applications, it can make life a lot
easier. Care should be taken that the program always keeps track of
where the output is going so that error messages don't end up in a user
file when they should have been printed on the console. Note that the
last argument to the $TYPE macro performs a similar function, but only
for the context of the call.
