+
+File: MACSYM,	Node: Primer,	Next: Syntax,	Up: Top, Previous: Manual
+
+You may start up an on-line tutorial for MACSYMA by typing
+
+:TEACHMACSYMA
+
+Or, if you have already started up a MACSYMA you may call the Primer
+from inside it by giving the command
+
+PRIMER();
+
+
+File: MACSYM,	Node: Syntax,	Next: Commands,	Up: Top, Previous: Primer,
+
+Input to MACSYMA is done with a syntax somewhat like that of Fortran
+or Algol.  All input lines are terminated with a semi-colon (;).
+
+Input lines are labeled consecutively starting with (C1), and then
+(C2), (C3) etc.  MACSYMA results are labeled from (D1) on.  Thus (D1) is
+the result of the computations performed by MACSYMA on the user's
+input string (C1).  These line numbers may be used to refer to
+expressions.
+                                2
+For example:  The expression   X  + 2 X + 1
+
+would be typed in as: x^2+2*x+1;
+
+Commands to MACSYMA take their arguments inside parentheses, e.g.
+
+FACTOR(x^2+2*x+1);
+
+Commands may be typed in upper or lower case.  The symbol % may be used
+to refer to the last expression MACSYMA computed.  E.g.
+
+(C1) (x+3)^5;
+					  5
+(D1) 				   (X + 3)
+
+(C2) expand(%);
+		   5	   4	   3	    2
+(D2) 		  X  + 15 X  + 90 X  + 270 X  + 405 X + 243
+
+The Mathematical operators used by MACSYMA are:
+  !  for Factorial,
+  ^ or ** for Exponentiation,
+  *  for Multiplication,
+  .  for non-commutative multiplication (spaces must go on either
+	side of the dot)
+  /  for Division, 
+  +  for Addition, and
+  -  for Subtraction.
+
+For more details see the SYNTAX section in the Primer.
+
+
+File: MACSYM,	Node: Commands,	Next: Demo,	Up: Top, Previous: Syntax,
+
+MACSYMA itself provides some on-line help.  Here are some useful commands
+to get you started:
+
+APROPOS(string); takes a character string as argument and looks at all
+    the MACSYMA names for ones with that string appearing anywhere within
+    them.  Thus, APROPOS(EXP); will return a long list of all the flags
+    and functions which have EXP as part of their names, such as EXPAND,
+    EXP, EXPONENTIALIZE.  Thus if you can only remember part of the name
+    of something you can use this command to find the rest of the name.
+
+DESCRIBE(cmd); prints out information about "cmd", which may be any
+    MACSYMA command, switch or variable.  Certain key words have also been
+    included, where they seem appropriate, thus DESCRIBE(TRIG); will print
+    out a list of the trig functions implemented in MACSYMA.  See also
+    APROPOS(string) which allows you to locate command names even if you
+    aren't sure of the full name.
+
+OPTIONS(); enters the OPTIONS interpreter which is a structured list
+    of MACSYMA commands.  You type the number of the subject of interest,
+    followed by a ";" to see the list of commands available for that
+    subject.  To move back up the list the command BACK; will go back up
+    one level, and TOP; will get you back to the original entry list.
+    EXIT; will quit out of OPTIONS.  DESCRIBE may be called inside OPTIONS
+    on the commands listed, either by number or by name.
+    OPTIONS(command); will give the various commands and switches
+    associated with command.
+
+EXAMPLE(command); will start up a demonstration of how command works
+    on some expressions.  After each command line it will pause and wait
+    for a space to be typed, as in the DEMO command (type N to see the
+    DEMO command).
+
+
+
+File: MACSYM,	Node: Demo,	Previous: Commands,	Next: Save,	Up: Top
+
+There are two commands which are useful for finding out how MACSYMA
+works on specific types of problems: DEMO and BATCH.  BATCH is also
+useful in programming.  These two are essentially the same command,
+except that the DEMO command pauses after each set of command/display
+lines and waits for the user to indicate readiness for the next pair
+by typing a space.  Typing anything besides a space will terminate the
+demonstration.  (Note: on noisy phone lines, the phone line may type a
+"rubout" (^? on some terminals) which terminates the demo.  In this
+case use the BATCH command to run demonstration files.)
+
+DEMO(name1,name2,device,directory); starts up a demonstration.
+
+To obtain a list of some interesting demonstrations, do
+LISTFILES(DEMO); which will list the "DEMO" directory.  To use the
+DEMO command on a file from this directory, for instance, "BEGIN
+DEMO", you proceed as follows: On the list printed out by
+LISTFILES(DEMO); you will see the line:
+
+[BEGIN, DEMO, DSK, DEMO]   5/2/81  L=335 chars.
+
+The four words inside the square brackets are what you place inside
+the parentheses as arguments to the DEMO command, e.g.
+
+DEMO(BEGIN,DEMO,DSK,DEMO);
+
+The remaining information on the line is the creation date of the file and
+its length.
+
+To run this demonstration using the BATCH command, you would type:
+
+BATCH(BEGIN,DEMO,DSK,DEMO);
+
+
+File: MACSYM,	Node: Save,	Previous: Demo,	Next: Helpme,	Up: Top
+
+There are several ways to store a MACSYMA calculation or partial
+results on disk to return to at a later date:
+
+SAVE([optional file spec],arg1, arg2,...,argi) saves quantities
+    described by its arguments on disk and keeps them in core also.  The
+    optional file spec is in the form NAME1,NAME2,DSK,DIRECTORY and is
+    enclosed in square brackets, e.g.  [JAMU,FUNCS,DSK,USERS2].  If you
+    omit the file spec, MACSYMA will select a file name for you consisting
+    of the first three letters of your login name followed by a digit (the
+    lowest digit which will give a unique file name).  The second file
+    name will be a number.  The arg's are the expressions to be SAVEd.
+    ALL is the simplest, but note that saving ALL will save the entire
+    contents of your MACSYMA, which in the case of a large computation may
+    result in a file which is too large to be reloaded.  VALUES,
+    FUNCTIONS, or any other items on the INFOLISTS may be SAVEd, as may
+    functions and variables by name.  C and D lines may also be saved, but
+    it is better to give them explicit names, which may be done in the
+    command line, e.g.  SAVE(RES1=D15); Files saved with SAVE should be
+    reloaded with LOADFILE.
+
+FASSAVE(args) is similar to SAVE but produces a FASL file in which
+    the sharing of subexpressions which are shared in core is preserved in
+    the file created.  Hence, expressions which have common subexpressions
+    will consume less space when loaded back from a file created by
+    FASSAVE rather than by SAVE.  Files created with FASSAVE are reloaded
+    using LOADFILE, just as files created with SAVE.
+
+LOADFILE(fn1, fn2, DSK, directory) loads a file as designated by its
+    arguments.  This function may be used to bring back quantities that
+    were stored from a prior MACSYMA session by use of the SAVE or STORE
+    functions.
+
+STORE(args) same as SAVE but doesn't retain quantities in core.
+
+RESTORE(file-specification) reinitializes all quantities filed away
+    by a use of the SAVE or STORE functions, in a prior MACSYMA session,
+    from the file given by file-specification without bringing them into
+    core.
+
+
+File: MACSYM,	Node: Helpme,	Next: Helpers,	Up: Top,	Previous: Save,
+
+In MACSYMA there are a number of commands which will allow you to
+communicate with the Mathlab Group or other MACSYMA Users:
+
+SEND("message");	- will send your message to some MACSYMA
+			system programmer who is logged in at that
+			time.  Note that message must begin and end
+			with double quotes.
+
+SEND(username,"message"); - sends the message to a specified user.
+
+Expressions may be included by referring to them, outside double
+quotes, e.g.
+
+SEND("I am trying to integrate",D3,"but it runs out of core.");
+
+MAIL("message");	- will send mail to MACSYMA.  This may be used
+			to report problems or bugs.
+
+MAIL(username,"message"); - will send mail to a specific user.
+
+Expressions may be included outside double quotes, as with SEND.
+
+BUG("message"); 	- similar to mail, sends a message to MACSYMA
+			Mail.  This may be used for reporting bugs or
+			suspected bugs in MACSYMA.  Expressions may be
+			included by referring to them, outside double
+			quotes as with SEND and MAIL.

+MACSYMA 303 has just been created.
+
+GJC@MIT-MC 05/06/80 1816-EDT  To: INFO-MACSYMA-TRANSLATION
+The 4 argument version of ROMBERG, e.g.
+F(A):=(MODEDECLARE(A,FLOAT),ROMBERG(SIN(A*X)*(X^2-A*X+1),X,0,%PI));
+now compiles well, actually better than the three argument version.
+In this example F(3.3) takes 2.1 seconds to calculate uncompiled
+but only 0.022 seconds compiled.  Using a separate function for
+SIN(A*X)*(X^2-A*X+1), and compiling it, gives a timing of 0.032 seconds.
+P.S. the 4 argument version of INTERPOLATE works also.
+
+GJC@MIT-MC 03/09/80 0612-EST  To: INFO-MACSYM
+There is a version of CFFK's famous INTERPOLATE function on the NUMER 
+directory. The changes are that it now takes a macsyma (untranslated) 
+function as a functional argument in the 3 argument case. And a call 
+to it can be used in compiled code without loss of variable scoping. 
+These changes will also be made soon to PLOT2 and ROMBERG. If any users 
+have always wanted to write a function that took arguments in the neat
+way that these functions do I can show you the package I used to convert 
+INTERPOLATE. A demo, NUMER;INTPOL DEMO highlights these changes.
+
+GJC@MIT-MC 01/12/80 0035-EST  To: INFO-MACSYM
+NUMER;BATCH FASL has some functions in it that may be useful to users

+To aid in the introduction of polylogarithms, etc., when DIFF(F[N](X),X);
+is done and F has a GRADEF defined for it, then DIFF(F(N,X),X); is 
+attempted.  As an example, a GRADEF for the Bessel function %J[N](X)
+has been set up, so e.g. RATSIMP(DIFF(%J[2](X),X,2)); may be done.
+(The fact that this is implemented in terms of DIFF(%J(N,X),X) is 
+somewhat hidden here.)  (Compare with the example given in the manual on 
+p.72.  (Please note that the "RATSIMP" used there should be in line (C5), 
+not (C4).))  At this time, setting up the GRADEF via GRADEF(F[N](X),...);
+cannot be done.  The syntax GRADEF(F(N,X),...); must be used.

+can save you a lot of time. Please see the file SHARE2;NUMRCL INFO if

+MACSYMA 303 has just been created.
+
+GJC@MIT-MC 05/06/80 1816-EDT  To: INFO-MACSYMA-TRANSLATION
+The 4 argument version of ROMBERG, e.g.
+F(A):=(MODEDECLARE(A,FLOAT),ROMBERG(SIN(A*X)*(X^2-A*X+1),X,0,%PI));
+now compiles well, actually better than the three argument version.
+In this example F(3.3) takes 2.1 seconds to calculate uncompiled
+but only 0.022 seconds compiled.  Using a separate function for
+SIN(A*X)*(X^2-A*X+1), and compiling it, gives a timing of 0.032 seconds.
+P.S. the 4 argument version of INTERPOLATE works also.
+
+GJC@MIT-MC 03/09/80 0612-EST  To: INFO-MACSYM
+There is a version of CFFK's famous INTERPOLATE function on the NUMER 
+directory. The changes are that it now takes a macsyma (untranslated) 
+function as a functional argument in the 3 argument case. And a call 
+to it can be used in compiled code without loss of variable scoping. 
+These changes will also be made soon to PLOT2 and ROMBERG. If any users 
+have always wanted to write a function that took arguments in the neat
+way that these functions do I can show you the package I used to convert 
+INTERPOLATE. A demo, NUMER;INTPOL DEMO highlights these changes.
+
+GJC@MIT-MC 01/12/80 0035-EST  To: INFO-MACSYM
+NUMER;BATCH FASL has some functions in it that may be useful to users 
+who run MACSYMA while not being logged in.  Such things as checking 
+the status of a disowned running macsyma without stopping it.
+See the file NUMER;BATCH INFO.

+To aid in the introduction of polylogarithms, etc., when DIFF(F[N](X),X);
+is done and F has a GRADEF defined for it, then DIFF(F(N,X),X); is 
+attempted.  As an example, a GRADEF for the Bessel function %J[N](X)
+has been set up, so e.g. RATSIMP(DIFF(%J[2](X),X,2)); may be done.
+(The fact that this is implemented in terms of DIFF(%J(N,X),X) is 
+somewhat hidden here.)  (Compare with the example given in the manual on 
+p.72.  (Please note that the "RATSIMP" used there should be in line (C5), 
+not (C4).))  At this time, setting up the GRADEF via GRADEF(F[N](X),...);
+cannot be done.  The syntax GRADEF(F(N,X),...); must be used.

+See the "SUPER WINNING EXAMPLE" in the documentation for the macsyma 
+COMPILE command for turning expressions derived with macsyma into 
+floating point function definitions that you will then use in GRAPH2, 
+RUNGEKUTTA, ROMBERG, or whatever.
+
+GJC@MIT-MC 08/04/79 0147-EDT  To: INFO-MACSYM
+To see an example of fast numerical methods in macsyma, do
+DEMO(RGKTEST,MAC,GJC); .  It shows the usage of the compiler from macsyma, 
+and two ways of calculating (GRAPH2'ing) the solution of a differential 
+equation, formal and RUNGEKUTTA. 
+
+GJC@MIT-MC 07/26/79 02:56:58  To: INFO-MACSYM
+A program RUNGEKUTTA(F,X,Y,D) that is fairly winning
+when used in conjunction with GRAPH2 (X,Y, and D are arrays),
+resides as NUMER;RUNGE FASL. Documentation is in the file RUNGE USAGE .
+(*** For updated note on RUNGE_KUTTA, see this file, note of 06/07/81. ***)

+GJC@MIT-MC 07/08/79 15:47:02  To: INFO-MACSYM
+I have just added to the share2 directory functions that I have been 
+using for a while that are both fast and convenient when working with 
+declared floating point arrays and translated functions. There are 
+functions for tabulating and mapping over declared arrays, a Gaussian 
+quadrature formula, a simpson's rule for functions and one for arrays.
+If you tend to use PLOT2 and ROMBERG on the same functions, then these 
+can save you a lot of time. Please see the file SHARE2;NUMRCL INFO if 
+you are interested.
