RE: Two variables...one memory location

[Jerry Adams <Jerry@xxxxxxxxxxxxxxx>]

I have seen memory get "stepped on" or corrupted because of mis-definitions of the parameters between caller and callee, but this doesn't ring a bell.

I'm not sure if by procedure you mean an internal subprocedure, a separate program (CL or RPG), or perhaps a service program.  Perhaps code examples, especially the prototypes, if any, and the interfaces might help understanding.

The only way that I've been able to envision the result described is for the two parameters to have the same definition and, then, for the callee to use the same field name for both parameters.

Subject: Two variables...one memory location


I am calling a procedure that passes in 12 parameters.  Two of these parms are populated within the procedure and the new values are passed back to the calling pgm.  These two variables, when testing, are using the same memory address in the system.  As soon as one is assigned a new value they both are updated with the new value.

I have changed the order of the parameters, re-compiled, logged off and other various means of trying to resolve the address issue.  Can anyone tell me why the system might be assigning these two variables the same memory location or a way to avoid this?
