Binding column heading to variable not working

[Theju112]

Dear Scott and Team,

I have an issue while trying to bind a subfile column heading list to a variable.

So , below is how I have used the variable (ColumnHead):

The RPG code is as below:

Code: Select all

ColumnHead = 'Ln#,Sts,Customer,Origin,,'+                    
             'Cons,Container,BOL#,'+                         
             'Booking,Plan,Order,P/U,Ship,Time,'+ [b]HDiff[/b] +    
             ',OM' ;                                         
                                                             
              EXFMT     LDSA1W     

The issue is with Hdiff variable which is a string that will hold a dynamic value. The issue is that, the first time, the subfile grid is displayed, the headings are displayed as required. Then in the scenarios where the screen is re-loaded after a different value (The only variable element in this case is the Hdiff field) is assigned, the old heading column values persist.

In summary, the value assigned to the ColumnHead variable when the first Exfmt is done persists even when the next Exfmt with a different ColumnHead value is done.

Are the headings not refreshed each time, the exfmt is done?

Are you sure that you have the code in the proper place? (Do you do EXFMT LDSA1W anywhere else?)

I don't know your logic - but it would seem to me that you'd want to assign the column headings at the time that you build grid (subfile) LDSA4W.

Good luck

Each time you do EXFMT, the entire record format is wiped out and re-drawn, so the column headings are definitely re-done.

Here's an example that works for me... display file named COLHDGD:

Code: Select all

     A          R SFL                       SFL

After hitting enter, it changes the column headings and looks like this:

Please tell me what I should change to experience the same problem you're having.

Hi Scott,

Thanks for your guidance. I was able to get it working after moving the ColumnHead variable assignment before writing to LDSA4W.
Sorry should have thought of that.

I felt that the record format is not being re-drawn because the assignment before the Exfmt (which I showed in the code) worked in the first instance but not for subsequent executions of the same line. And yes, this is the only Exfmt in the whole program.

The program was put in debug mode with a breakpoint on the line with the Exfmt and I "manually" assigned a value to columnHeading (using Eval) before doing an F10. The column heading showed the value I assigned. Please note that there were no write operations done in between the "manual value assignment" and the Exfmt.

But when the control reached the Exfmt the second time and I tried the same, it didn't work. The previous heading was still displayed. So that was a bit confusing.

Anyways, thanks a ton for your quick response!!
