Re: Resequence data in file based on screen seq

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.
