RE: Inserting a record into the middle of a subfile--suggestions?

I have had very good luck with variable-sized arrays - Defined as an array of qualified data structures. Makes for quick dynamic sorting on different fields. Some cases the actual subfile is most (or all) just a large character field used for display - allows for a lot of flexibility or displaying tree-like structures or different formats for different records.

Subject: Inserting a record into the middle of a subfile--suggestions?

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...
