What makes you think a PUN file has 255-byte records?  If it was created
using the CMS PUNCH command, it can't be over 80.  If DISK DUMP or
SENDFILE, the physical records are still only 80, but the logical records
can be any length -- and you shouldn't have any trouble RECEIVE'ing the
file in either case.
