Re: Subfile reversing display

Hello Michael...

That might solve the problem, but it doesn't explain why on 39 programs
the procedure works fine and on the 40th it doesn't.

Have a good day.

Re: Subfile reversing display






Simple answer...

You are reading previous and adding to the subfile display as you read
backwards.

Solution...
When reading previous add to an array and put the first record read in
element 10. Then when finished output the array to the subfile.

Or
Read previous only to set the position of the file. Then use your forward
read loop to read the file again to populate the subfile.

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
