I have a couple of applications that do something similar: copying a subfile to an array, re-numbering and re-sorting
and the performance is good.

The sorting is flexible, based on an article by Paul Tuohy: "Those Weird and Wonderful Arrays" and uses
a pointer to switch between the appropriate data structure depending on what the user is doing.

If you are below a couple hundred records I expect you'll get good results.

copying to variable size array. why not also have the user have an edit mode screen' of the row to be updated?

I need to insert records into the middle of a subfile. The user can
enter a keyword that's attached to a long description and I need to
get that description into the body of the subfile.

I could add records to the end and then resequence when writing to the
database but that won't be satisfactory from a user experience
perspective--the user needs to see the full text in order as part of
the entry process. My subfile record length (including hidden fields)
is about
400 bytes and I should have less that 50 records most of the time. I
have four 132-character subfile records on the screen and already have
used the fold/unfold option.

Copying the subfile to a variable-size array, inserting the records
where needed, and then reloading the subfile is an option.

Another option is to have A/B subfile control/detail set up records
copy from the "A" subfile (+ inserts) into the "B" subfile and then
display the "B" control record. SQL temporary tables and
memory-resident tables are possibilities also.

Where's a linked list when we really need it?

I'll be grateful for any suggestions and wish you all a Happy New Year.

thx...
