Re: Problem Clearing Procedure Parameters

That was it Darren.

I have the screen fields defined on a couple of screens. The main procedure that was calling Procedure #1 was passing in the SFIELDA and SFIELDB from screen 1 for processing. Procedure #1 was receiving those fields as CONST into separate "independent" fields. Then Procedure #1 was calling Procedure #2 which was clearing the screen fields, thus clearing my "independent" fields from Procedure #1.

I remember this problem, because I encountered it once before many moons ago.

Okay, one more possibility. What are you passing as parms to procedure #1?
The field that you place in the call, is it some stand-alone field that
you've defined in the program, or could it be another display file field?
As someone else stated, CONST passes by reference sometimes, if it can, so
your procedure #2 could be playing with the value, without Procedure #1's,
or the main procedure's knowledge.

There are no parameters for Procedure #2. Procedure #2 gets called when
certain conditions are met. It only initializes some screen fields and
indicators.

It sounds like memory corruption to me. You're not using a level check *no
on the display file right? You're not placing the names of the actual
screen fields in a datastructure in your program? I'm not talking about
overlaying, just listing the field names in a datastructure.
