RE: Fixed v Free Display Variables

The procedure does not have a dcl-pi because nothing is being passed into it. Should there always be one? I also changed nothing about the program besides this specific procedure beginning, so the Qty shouldn't change or have a value added to it (maybe besides Qty being global or not as you suggested). - Jon Paris

The workstation f-spec is just: Dcl-F HazShpF Workstn;
- Dave Clark

Alan, that seems like good practice, long story short I'm the guy that tried to convert the programs to free-format and the other guy was curious because in fixed format the standalone variables with the same names would show up on the display file.

Thanks for all the helpful information,
Jeffrey Young

Whatever the problem it is highly unlikely (near impossible) for it to be a fixed/free issue. Under the covers the two are identical.

But you are obviously not showing all of your code because the dcl-proc should be followed by a dcl-pi and there isn't one there.

Variables within a subprocedure are local and therefore would not normally be available to display without copying it somewhere.

The fact that it has the same name in the subprocedure as it has on the file means you have _two_ versions of the field Qty in the program - one global (the file version) and one local (the GetHazmat version). The global version will always be the one used by any display file output (unless Data Structure I/O is used which is not th case here as Qty is a stand-alone.

All of which is to say that your fixed form version must have a value being placed in the global Qty field and you free version doesn't.

I have an interesting question. (very new dev here) Let's say my display file has a output field named Qty. In fixed format, the program declares a standalone variable Qty and sets the message. The display file shows the message when I run the program.

P GetHazmat B
D Qty S 40 Inz('G = Gallon, GP = 5 Gallon Pail')

However, if I try to do the same in free format, the message will not display. I assume because the Qty variable is being created again? But then why does it work fixed format? I know to solve the issue is just to not declare it again as a standalone in free format, but that doesn't solve my curiosity. Does anyone have some clarification?

Dcl-proc GetHazmat;
Dcl-S Qty Char(40) Inz('G = Gallon, GP = 5 Gallon Pail');

Thanks,
