! ABSTRACT: Routines to transfer records or blocks of file data.
!
!
! ENVIRONMENT: RMS-20, BLISSNET-20, XPORT-20, Non-Transportable code.
!
! AUTHOR: Andrew Nourse, CREATION DATE: 14-Sep-82
!
! RMS edit numbers:
! 631 - GJ%FOU on destination RNAMF JFN.
! 625 - (GAS, 10-Jun-86) Dot bug caused low memory to be trashed after the
! RNAMF in RL$RENAME
! 566 - Remove redundant Rl$Directory routine
! 562 - Handle errors better in wildcard case
! 544 - $parse needs another UaPointer call
! 542 - Set CHA bits first time thru $Search
! 516 - Add UAddr calls for ext addr
! 514 - Use MapCodes for all GTJFN errors
! Module edit numbers:
! 13 - RMS'ify and convert to vaxish name block
! 12 - Don't trash JFN when no nam block is being merged in really
! 11 - Check RLF bit, not presence of an RLF, in RL$MERGE
! 10 - Make wildcard $RENAME work
! 07 - Set NAM$V_FNB_WILDCARD if any wildcard bit set in RL$MERGE
! 06 - First file on next filespec was not being processed correctly
! 05 - Use RMS BSZ instead of FDB BSZ if it is an RMS file
! 04 - Fix wildcard delete and rename
! 03 - Put in ENTRY points
! 02 - Supress device we get from JFN always if remote file
! 01 - Separate system-dependant functions of DIRECT into this module
