! 12 - Add TOPS-10 support [Doug Rayner]
! 11 - Put nodeid in resultant name generated from 3-part name
! 10 - Send real byte size to 36-bit machines, no byte size to others
! and include node name in remote resultant filespec.
! 07 - Set implied CRLF for ASCII FIXED
! 06 - Workaround RSTS not sending STATUS for file-not-found on directory
! 05 - Put in ENTRY points
! 04 - Fix default for BLS in DAP$PUT_ATTRIBUTES
! and put in bitvectors for workarounds
! - Fix RENAME name type
! 03 - Page mode
! 02 - Make the FOP go out
! 01 - The beginning
