You could write a trigger program to be executed when the record is

Check the number of records currently in the file, and delete the
oldest one if your limit is reached.

Do you know if the file information data structure will accurately
reflect the number of records if used in a trigger program?

I'm a little unsure about the exact behavior of trigger programs. If
there is a before-insert trigger on a file, do subsequent adds have to
wait for the trigger program to complete? I'm not sure whether the
situation will ever arise that there are, say, 105 records in a file I
intend to contain only 100. I'm trying to ask whether I need to code the
trigger program to delete one record at the beginning if needed, or to
code it so that it deletes numrecords - n at the beginning.

Thanks for the help.
