If you're passing (display) file fields as parameters, and they are changing on the display, then every subsequent procedure that those fields were passed to will have their parameters "change." When you define a parm as Const, you are passing the address to the parameter on the procedure call.
Hopefully this is the case for you, because then the fix is relatively easy: either change the parm keyword to Value or move the file field into a variable and pass that instead.

Subject: Problem Clearing Procedure Parameters
I have a program that has two internally defined procedures.
Procedure #1 has two fields as input parameters, FIELDA and FIELDB, both defined as CONST. In Procedure #1, the two input fields are moved into two fields on a screen called SFIELDA and SFIELDB. If certain conditions are met, Procedure #1 calls Procedure #2. In Procedure #2, the two screen fields, SFIELDA and SFIELDB, are cleared. I noticed that the fields passed into Procedure #1, FIELDA and FIELDB are getting cleared at the same time. I put the program in debug and verified this.
How is this possible? First of all, I thought if a parameter to a procedure was defined as CONST, it couldn't be changed. I have searched through the program to make sure there were no datastructures, etc. that might be overlaying the fields and the DDS for the screen to make sure the procedure parameters are not defined on a screen.
Any advice and/or help would be greatly appreciated.
Thanks,
Robert
