And if it did work I don't see how its performance would be any different than using MAX page down (PF8). As a flag (QSAM) file the only way to reach the end of the file is to read each record.

An IDCAMS print would seem the most accurate, just put output to a DD DUMMY or you might never compete the run for a large file. There may be a message with how many records were written to the file in a the log of the job that wrote it - if still available and the program or utility used displayed this information.

Goto ISPF browse on the file
L 9999999
Locates the last line
I think it’s quicke than using max but haven’t tested it
The other space calculation methods may give you approximations.

Now if you are talking about doing it programatically - that is another story. Simply view the file under ISPF, max to the bottom, and look left to the last line number - BINGO.

Using the same space requirements as your original file, repro the file to a new file. The output from your JCL should give you the exact number of records copied from the one file to the other. Another way is to use a SELCOPY, but the REPRO will be the quickest of the two. Hope this helps. I would use an IDCAMS REPRO.
