The meaning of the code you wrote is, if I correctly understand, 'assign
to "callmacro" a call of a "multiplo" macro, with 3 arguments : a, b,
and a*b'.

I guess you may prefer this kind of thing :

<assign|multiplo|<macro|a|b|<arg|a>*<arg|b>>>

(assign to "multiplo" a macro which takes 2 args (named "a" and "b") and
is evaluated as "arg a *  arg b".)

Note that you will produce "<arg|a>" by typing "\a<return>".

<multiplo|x|y>

(call "multiplo" with "x" and "y" as arguments)

Happy TeXmacsing.
François
