I've had this problem before.
What you are doing is decreasing the relative record number by 1 and
writing the sub file record.
However, the write of the sub file record is NOT dependent on the RRN (why
- I don't know)
I have since NEVER used that practice
What I do is readp the file in question for the number of lines displayed
on the sub-file and then read forward, populating the sub-file ONLY on a
read, NEVER on a readp.

Hello Jeff...

The relative record number is already set to 10 and decrements by one for

each record read. I verified it dropping down during the debug process.

Have a good day.

Re: Subfile reversing display






When you are loading the subfile for a previous page, you need to start
at

RRN number 10 and work your way down to 1. Not 1 up to 10.

Subfile reversing display






Hello all...

I'm running into a really weird situation and I'm wondering if anyone's
ever encountered it before.

We're generating a subfile with 10 records (one page at a time, subfile
size and page = 10), nothing fancy, with both regular and hidden fields.
There are no issues with writing the records themselves.

When paging down (using the roll-up), the records proceed forward 10 at a

time in ascending sequence.

If, however, the page up key (roll down) is used, the records appear in a

reversed order - the correct records appear, just out of sequence. I've
included an example of what's happening:


Screen - starting position:

A Record
B Record
C Record
D Record


Screen after paging down:

E Record
F Record
G Record
H Record


Screen after paging up

D Record
C Record
B Record
A Record.

If we were now to hit the page down key again, we would get

E Record
F Record
G Record
H Record


The procedure is pulling the correct records, it's just not displaying
them in the proper way.


This subfile procedure is used in a number of programs. I use it any
time


we need a subfile - basically cloned code. None of the other programs
that use this code are having the same issue - there are around 40
different programs using it. The logical that is used during the fill of

this particular subfile is not unusual - a three key index with ascending

controls on the keys - there are no omit or select functions. I have
checked the logical to verify the index properties.

I've checked the clear and display of the subfile and there are no
indicator issues.

I've stepped through the code with the debug procedure and watched how it

is writing the records, verifying the contents of each record's fields
and


the relative record number associated to the record being written - there

are no issues and the relative record number is being properly assigned.

Any ideas?

Have a good day
