Hey Lora,

I don't see anything that might help you. Can you post the definitions from
working storage or file definitions? That way we can see field types and
sizes and such.

Hi, Jim,

Actually, I suspect many of my questions are very basic. I'm
struggling to deal with the DFHCOMMAREA, and trying to understand why
it's behaving the way it does.

For instance, the primary function of the screen I'm building is to
read a VSAM file sequentially, and find all records with the same
employer account number. They'll be displayed in descending order.
When the account number changes, I stop displaying the data.

Thus, I use a Startbr, Readnext process to read through the file.
This works perfectly when moving forward. With each press of the
Scroll Forward key, a new screen of records is displayed.

For debugging purposes, I display the account number, and the first
and last key that are on the screen on the bottom line of the screen,
to prove that these values are being stored in the DFHCOMMAREA. They
are as I move forward through the file.

The problem occurs when I press the key to start scrolling backward.
At that point, the account number is replaced by spaces. I know why
this happens, because I write it to the DFHCOMMAREA each time I
execute a successful startbr, and the program is failing on the
STARTBR when going backward.

In addition, the first key on the screen, the one I'll need to use to
start the browse backward, seems to become corrupted. The first four
characters of the 24-byte key are replaced by spaces, and the fifth by
a B, though I have no idea where that comes from, since the key is
entirely numeric, though it's stored in an alphanumeric field.

Because this key is now invalid, when it's used in the STARTBR
operation, the start browse fails.

Yet just before I pressed the Scroll back key, that key was displayed
properly on the screen, so I have no idea what happened to it.

The code for the Scroll backward process follows:

00136 IF EIBAID = DFHPF3
00137 PERFORM 7100-CLEAR-SCREEN THRU 7100-EXIT

Lora,

I think your questions are just fine here, as long as you realize that
there may be some differences between i5/OS COBOL (even the CICS
version) and what you are doing on a mainframe. What we have to offer
may or may not help.
Ask away, and if we can, we will answer to the best of our knowledge.
