How to do addition in SPSS macro

[jagadishpchary]

Hi:

Might be it is a easy one. However I am unable to find the solution. Actually I am looking for a syntax in Macro where I have to add two passing variable i.e.

!LET !f = Sum (!ARG1,!ARG2)
OR
!LET !f = !ARG1 + !ARG2

the above syntax's are not working. So can any one let me know the correct/workable solution for my query.

Note: No new variables should be created in this process.

Thanks.

You would think it would be an easy one (I'm sure there is plenty of posts on this subject in the archives)...

Can't get a more comprehensive guide on this than:

The best solution is to use Python programmability for this sort of thing.

"/* This code cannot be encapsulated in macros called from other macros. This
/* is because assignments such as  "!let !a = !add(6,2)"  do not work; SPSS
/* will not recognize any tokens following the macro name "!add"."

Not to be a contrarian or anything but the above is REALLY not the case if you think about it a bit  or maybe a lot? or way too much, ( certainly helps to be a bit mad ;-))).
I posted code on MACRO return values sometime last year (or was it the year previous?).
----
SET MPRINT ON PRINTBACK ON.
DEFINE !Add (!POS !TOKENS(1) /!POS !TOKENS(1)/!POS !TOKENS(1))
!SUBSTR(!UNQUOTE(!3),3) !LENGTH(  !CONCAT( !BLANKS(!1),!BLANKS(!2)  ) ) .
!ENDDEFINE.


DEFINE !Caller (!POS !TOKENS(1))
!IF (!1 !EQ ?) !THEN
!ADD 1 3 '/*!Caller' .
!ELSE
ECHO 'In Main'.
ECHO !QUOTE(!1).
!IFEND
!ENDDEFINE.

!Caller ? .
