On-Exit not working with Debug first time through

I have a procedure that returns a zoned(5) field and it is working as expected.

However, if I have debug active, the first time through the return value appears to be getting corrupted in the on-exit routine.

My calling program ends up getting a data decimal error.

Subsequent calls while in debug returns the expected value.

If I comment out the return op-code within the on-exit routine it returns the expected value. Once I add it back I start getting bad values on the first call when in debug again...even though inerror is not set and it is not executing that code.

I've went through starting / calling / ending / calling / starting / calling / ending. Always after starting debug the first call returns a bad value.

Thoughts?


dcl-c c_rtnErrVal const(-1);

...

On-exit inerror;

If inerror;
...do stuff
Return c_rtnErrVal;
Endif;

End-proc;
