Re: [COBOL400-L] Display data not getting to program

My COBOL is rusty at best. However, I'm certain that the F-keys need to

be

defined as CFnn in the DDS.

I'm sure you already know this, but, you know, gotta ask the stupid
question: Are you certain that you are reading the display format with

the

data you are trying to get? It seems that you are under certain
circumstances, but not others?

If you don't get any other takers on this thread, you may need to post

the

relevant source for the COBOL and DSPF.

Dan is correct. In the display file (DSPF) you code the available function
keys. A CAnn specifies an 'Command Attention' key. The returns the record
but does not contain the data entered by the user--also, no field
validation is performed. Coding CFnn specifies a 'Command Function'
key--data is returned to the program. Even with a CFnn if you've coded the
function keys on the control and the footer, they have to be coded the
same. It can depend on the order you write the Control and Footer records.
You'll need to specify the OVERLAY keyword on the record you write second.
Of course if you don't specify it, the first record is cleared from the
screen and the data fields might not be available for the user. There are
other keywords that can prevent the system from clearing the first record
written, but you still could have problems with the data not being
available. If you can't figure it out, you'll need to post some code as
Dan suggested.
