Re: Address of Variable in Service Program Exported Procedure

Variables declared in a procedure are only visible in the procedure.

You need to declare the variable globally and with the EXPORT keyword.
Then in the calling program, you declare it again with the IMPORT keyword.

But why do you need this? Why isn't RETURN'ing the variable good enough?

I'm sure there are valid use cases, but they are few and far between IMHO.

Hi,

We have an exported procedure in a Service program (RPG) which needs to
pass back the address of a variable, so that the calling program can
use the value in that variable.

Can the calling program (RPG) access the value of the variable if it is
defined within that exportable procedure, or does the variable need to be
'global' in the Service Program?

TIA
Vinay
