Display not refreshing

[colonel_buck]

I am trying to write a simple COBOL program to display a simple screen. The 1st write to the display file works fine, but subsequent writes are not. It appears to be writing the 1st record every time I press Enter. I've written the code just like it says in the books I have, but it still does not work. Any ideas?

There may be some code samples over here:

Re: Display not refreshing

Also it might have something to do with the way you are reading your file. Perhaps pasting the part of the code where you are accessing the file and moving the values to the display file fields would help.

Re: Display not refreshing

From the code I do not need where exactly you are reading the file. It looks like you are just refreshing the date and time alone. Unless this is not the whole code.

0140.00 Perform 900-Open-Files.
0141.00 Perform 800-Init-MDM4501R.
0142.00 Perform 902-Write-Display-Record.
0143.00 Perform 903-Read-Display-File.
0144.00 Perform 100-Process-Screen Until WS-FUNCTION-KEY-03.
0145.00 Perform 901-Close-Files.
0146.00 Stop Run.


100-Process-Screen only does the display of the screen. I do not see any logic to read from a file.

Re: Display not refreshing

Sorry... my eyes are hurting when trying to read your example

If you contact me offline and send the source code for your DSPF and program, I will look at it...
