Following are the instructions for loading an ASCII file to an
|
|
MPX-1.X system. It is assumed that the reader has compiled the
|
|
utilities in the taptools directory using the provided makefile.
|
|
Filenames on MPX-1.X must be 8 chars or less.
|
|
|
|
1. Create an ASCII file on Windows or Linux using your favorite editor.
|
|
The EDIT program on MPX works with numbered or unnumbered text files.
|
|
Each record in the text file uses columns 1-72 for text and columns
|
|
73-80 for a line number (xxx.xxx). This is 80 column card format.
|
|
|
|
2. To convert a newline terminated file to an MPX file use the utility
|
|
"renum" included in the taptools directory. Lines in the file will
|
|
be expanded to 72 characters or truncated to 72 characters. The
|
|
carriage return characters (\r) will be removed and lines will be
|
|
terminated with a newline (\n). Line numbers of the form (xxx.xxx)
|
|
will then be appended to the text line to create the card format.
|
|
/somewhere/renum <textfile >cardfile
|
|
|
|
3. The next step is to convert the card image text file to an MPX
|
|
blocked file format. This involves removing the carriage return
|
|
character and then encoding the line into the blocked format.
|
|
The block file format is the standard file format for MPX.
|
|
/somewhere/mpxblk <cardfile >blkfile
|
|
|
|
4. Once we have the files converted, the next step involves creating
|
|
a FILEMGR formatted save tape. The output file will be in SIMH
|
|
.tap simulated tape format. The tape can then be read by the
|
|
FILEMGR on MPX to load the files into the desired directory.
|
|
The file system on MPX is a flat file where all files are in
|
|
the same file system. A username is used to separate files for
|
|
each user. A blank filename implies the system directory.
|
|
/somewhere/mkfmtape -t -u username usertape.tap file1 file2 ...
|
|
Valid options are:
|
|
-p : use file type 0xca for executable programs
|
|
-t : use file type 0xee for text files
|
|
-l : use file type 0xff for library files
|
|
-a : append current files to output tape
|
|
-u username : the username (directory) for the files
|
|
|
|
Make sure the usertape.tap file is assigned to the tape drive
|
|
in the .ini file or use the following commands at the sim>
|
|
prompt for SEL32.
|
|
hit ^E to get the sim> prompt.
|
|
sim>detach mta0 remove current assignment
|
|
sim>attach mta0 usertape.tap assign your restore tape
|
|
sim>go
|
|
|
|
5. Boot MPX-1.X. Input @@A to get OPCOM prompt ??. Use cap lock for
|
|
uppercase input. Type "EXIT" to OPCOM prompt to get a TSM> prompt.
|
|
If you type WHO, TSM will display your current logon information.
|
|
|
|
TSM>WHO
|
|
ADDRESS OWNERNAME USERNAME
|
|
======= ========= ========
|
|
*TY7EFC CONSOLE
|
|
|
|
The username will be blank for system directory. Use the command
|
|
TSM>USERNAME JOHNDOE to set username to the one specified in the
|
|
-u option above or just TSM>USERNAME to make it blank. There is a
|
|
command file on MPX that is handy to restore files from tape that
|
|
does the device assignments to the FILEMGR program. The file is
|
|
FMGR and can be run to input files from the assigned tape. MPX-1.X
|
|
has been SYSGEN'd to have 4 tape drives defined at 1000, 1001, 1002,
|
|
& 1003. SIMH names are mta0, mta1, mta2, & mta3. So attach the
|
|
restore file to mta0 as show above. Now execute the FILEMGR program.
|
|
TSM>FMGR 1000
|
|
TSM>FMGR 1000
|
|
* * * F I L E M A N A G E R * * *
|
|
FUNCTION USER NAME FILE NAME DEVICE START LENGTH SPEED
|
|
(FIRST BLK) (# BLKS)
|
|
|
|
FILEMGR output will be assigned to the terminal and tape input from
|
|
device MT1000. The FILEMGR will output a heading and then the FILEMGR
|
|
prompt FIL>. At this point you can use the command FIL>SAVELOG to
|
|
list the files on the tape or you can use the command FIL>RESTORE to
|
|
restore the files to the disk. You can then type EXIT or X to the
|
|
FIL> prompt to exit the FILEMGR.
|
|
FIL>RESTORE
|
|
RESTORE JOHNDOE FILE1 DM0800 234656 1052 SLOW
|
|
FIL>REWIND IN
|
|
REWIND (IN)
|

|
If you would like to see your files listed in the system, use
|
|
FMGR again without any parameters. Then use LOGU to log your
|
|
username files or LOG to log all files.
|
|
TSM>FMGR
|
|
heading here
|
|
FIL>LOGU
|
|
LOG JOHNDOE FILE1 DM0800 234656 1052 SLOW

|
|
all files list here
|
|
|
|
6. You can use the program EDIT to view or modify the file. At the
|
|
TSM> prompt type EDIT XX, where XX is a two character editor
|
|
workfile name. It will show up in the directory listing as XX*WRKFL.
|
|
At the EDT> prompt type USE FILE1. You will get another prompt when
|
|
the editor is done reading the file. Hit return to list the file.
|
|
|
|
TSM>EDIT XX
|
|
BEGIN TEXT EDITOR
|
|
XX*WRKFL CLEAR
|
|
EDT> USE FILE1
|
|
File listing will be here.

See the MPX-1.X reference manuals for the other FILEMGR and EDIT commands.
