Yes - the subfile image is kept in the program's memory. I've also done it using User Spaces for cases where a "reference" type subfile can be shared by multiple users.

The technique is explained here: <> I'm sure I've rewritten that in a more modern style but can't find the reference. That one uses a fixed array size but the technique with dynamic memory is the same.

As I said in my response to Jerry - I do load alls into memory - so positioning, sorting, etc. is really not a problem.

Can you please elaborate? I don't understand "into memory" in context of the system's single level store. Are you maybe talking about an array in whatever HLL you're using?
