Maxima Manual
5.1 Introduction to Expressions
There are a number of reserved words which cannot be used as
variable names. Their use would cause a possibly cryptic syntax error.

Most things in MAXIMA are expressions. A sequence of expressions
can be made into an expression by separating them by commas and
putting parentheses around them. This is similar to the C
comma expression.
| | (C29) x:3$
(C30) joe:(x:x+1,x:x*x);
(D30) 16
(C31) joe:(if (x >17) then 2 else 4);
(D31) 4
(C32) joe:(if (x >17) then x:2 else joe:4,joe+x);
(D32) 20
|
Even loops in maxima are expressions, although the value they
return is the not to useful DONE
| | (C33) joe:(x:1,for i from 1 thru 10 do (x:x*i));
(D33) DONE
|
whereas what you really want is probably is to include a third
term in the comma expression which actually gives back the value.
| | (C34) joe:(x:1,for i from 1 thru 10 do (x:x*i),x);
(D34) 3628800
