Hi mfuser,

As you are not mentioned about the language, I am explaning with PL1.

Mostly we will use functions for returning values to the calling programs.
For example, you want to calculate X1+X2 and want return the value in SUM1

Code:
RESULT = SUM_FUNCTION(X1,X2,SUM1)
...
...


SUM_FUNCTION:PROC(X1,X2,SUM1) ;
DCL X1 DEC FIXED;
DCL X2 DEC FIXED;
DCL SUM1 DEC FIXED;

SUM1 = X1+X2;

RETURN(SUM1);
END;


Hope this will help you...
