Hi Gene,
Don't laugh!!! <G> But here is an "ugly" CL program, I wrote a few years
ago to RGZPFM files that > 15% deleted records.
We auto-scheduled it to run on the weekends over selected libraries. It worked
well, but we never had files with millions of
records either.

Please respond to
RPG400-L
Also ... the big time consumer is still there .. REORGING THE FILES .. to
recover the DASD..! .. This process is dependent on the number of Logical
files as well as the size of the original physical file! .. This is still my
favored archiving solution.

Whoops, I forgot to add: Delete the 'K' on Terry.Rhoades example file specs
so the files will process in arrival sequence!
