In Edita, I just use db_table_size(), never delete any records in the
main
program, and have a separate standalone utility which runs in
single-user=20
mode and looks for items which ought to be deleted (in this case source
files
and directories which no longer exist and have no backups). If it finds
any it=20
loops through the whole db replacing <high> with <first unused slot>.
A simpler (but slower) way is just to have a separate record which
contains
a counter and is rewritten every time you add a record. You could reduce
the
overhead by adding say 10 to the counter, and then the next 9 record
adds do
not need to rewrite the counter record, and possibly release any unused
slots
on successful program shutdown.

Pete
