$NEWPASS is (and has always been) no different from any other MPE file in
terms of LIMIT, so far as I know.

The default MPE LIMIT is 1023 records if none is specified.

The MPE CI I/O redirection function requests a LIMIT of 10,000 records, so
if you redirect a CI command to $NEWPASS with ">" then the limit on the
resulting file will be 10000.

I think CM USL files had an adjustable internal limit that could come into
play when creating really big CM programs or libraries that you might be
remembering.

Other things may specify different limits when they open the file of course,
and you can override most of them with file equations.

These days the default 1023 limit is pretty useless, but arbitrary limits
like 10000 are just really annoying.  I guess 1023 wasn't enough for
whomever was developing the CIOR stuff, but 10000 *was* enough for whatever
tests they were doing.  Of course the 10000 overflows unexpectedly just
about as often as 1023 would.

These days the LIMIT of a file doesn't have a huge impact on the disk space
or other resources it needs (hence the C libraries that create bytestream
files use 2GB as their LIMIT).
