I can think of several ways of doing this, take your choice!

1. Change whatever builds the subfile to include more realistic data
definitions instead of just one big 500 character chunk. Then access the
subfile in Quick and do whatever you need to do. You should probably use an
indexed subfile in this case.

2. Define a direct file in your data dictionary with the appropriate record
layout (totaling 500 characters). Point the open name from the dictionary
(something generic?) to the subfile with a file equate and then you can read
and update (but not delete).

3. Create a bunch of temporary items in the Quick screen and load them up in
the postfind procedure using the substring function. In the preupdate
procedure you can stitch the 500 character chunk back together from the
temps.
