Let me clarify what I am attempting to do.
I have a file with the key: Company, Location, Item, Seq#, Substitute Item.
The file has additional fields.
The user sees all substitute items for the Company, Location, Item and can change the Sequence # and other data shown.
Since the user can change the sequence #, I need to process all records for the group.
When I do the update/add, I need to resequence the data on file based on the seq# the user keyed.
This is similar to what is done in SEU when you insert or delete lines.
What I am doing now is storing the screen seq# & substitute item in an array, sorting the array and then deleting all records for the group.
When I output the records from the subfile, I assign a sequence # based on the location of the seq#/item in the array.
I was hoping for a less messy method to get the same result.
Thanks,

Hi Jeff
I suppose it depends on what your definition of simple is.
Anyway, the method I use is independent of version.
Load the database records into the subfile, where each subfile record has
the keys (original sequence #) as hidden fields.
The user then changes the data displayed (add/change/delete)
When the user decides to update the database (through a function key)
chain through the subfile from rrn 1 to not %found
Using the hidden fields as keys to the database record, chain the database
file
if the record is not %found, write the database record based upon the data
on the subfile record
if the record is %found
if the sub file record shows that it is to be deleted (sequence # =
zero (or blank or whatever) delete the database record
otherwise
change the database record appropriately from the sub file record and
update
Hope this helps

Does anyone have a simple method to resequence data in a file based
on the new sequence # on a screen?
I am limited to V5R1 with any concepts used.
The file has a sequence # as part of the primary key.
The user will see a subfile of all records in the file with the
sequence # available to be changed.
In addition, they can add records and specify any sequence # they choose.
Add, Change and Delete are all done in one pass.
