Re: Resequence data in file based on screen seq

[Alan Shore <AlanShore@xxxxxxxx>]

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
