Returning values from functions

david.weeks

Hello All

I have created a function where i pass two fields into this.
Once I have performed some calculations within the function, I want to send back a boolean variable that I will set within the function.

How do I access this variable?
i.e. I see there is a return value section when setting up the function but how does it work?

Thanks

Hi,

You have three fields:
"return type" and "length" set the type of the returnvalue.

if you use the field "name" (e.g. RetVal) then you can assign the field a value as variable: Retval := TRUE; or RetVal := 'Hello';

if you leave the field "name " empty, then you can use the returnvalue with EXIT(TRUE); or EXIT('Hello');

Hope this helps,
Frank

And you call a function like this:
bMyResult := MyFunction(parm1,parm2);

If you ever need to return more then one result, you can use a parameter called by ref. (VAR=Yes on parameters definition).

This way all changes that are done to this parameter are visible outside function.
