Module name:      PROJECT MAGTAPE BACKUP UTILITIES

New facilities:
---------------

   >> V0301 << of MT_SAVE & MT_LOAD

   -  Possibility of using more than one tape for the same save/load.

      When the tape is out, the user is informed of it and asked to tell
      if there are more files to save/load. If the answer is no, the
      saving/loading is terminated and else the user is asked to mount
      the next tape and tell if this is done. If the answer is no, the
      saving/loading is terminated and else it continues with the next
      tape. The current volume number is output above the listing of files
      on current output/log file.

   >> V0201 << of MT_LIST, MT_SAVE & MT_LOAD

   -  The configuration parameters are fetched from a disk file.
      This solution is more flexible and makes it possible to
      support all kinds of MX-AMOS installations.
      The name of the disk file is

      MT_CONFIG.T

      and it must reside in the same directory as CSS/181.

      This file must be edited to contain two lines :

      D:<device addr> <NL>
      R:<RAM    addr> <NL>

      where <device addr> is an integer with three compartments
      bit 12-15 : crate no (AMOS & XAMOS : 0)
      bit  6-11 : 0
      bit  0- 5 : device address (AMOS & XAMOS : #1F)

      and <RAM addr> is an integer stating the start address of the
      magtape controller RAM in units of one K relative to start of
      crate (AMOS & XAMOS : 240(page 3 version) or 176 (page 2 version)

   >> V0201 << of MT_SAVE

   -  A search mask for non-directory files:

      M: <mask> {,<mask>}

      <mask> is a string consisting of letters,digits and '?','+','-' and '#'
      '+' may begin a string and indicates that the mask is a plus mask
          (this is the default for a mask, if not started with '+' or '-')
      '-' may begin a string and indicates that the mask is a minus mask
      '?' means any character
      '#' means any (perhaps empty) character string

      Examples: AB#, #C#, #.???, AMOS.D, #, -#.LIS, +MYFILE#

      Semantics:

      Only filenames that fit to the search masks are saved.
      Several masks can be specified in which case the names must conform
      to at least one of the masks to be saved.
      The plus masks and the minus masks work like this: A name hits the set
      of masks, if it conforms to at least one of the plus masks and none
      of the minus masks.
      Note in particular that a specification of masks containing minus
      masks should at least contain one plus mask.

   -  An exclude mask for directory descents, meaning that
      directories with names fitting to the mask are not searched.

      X: <mask> {,<mask>}

   -  A compress option, meaning that a file is only copied once in
      compress mode but you may want to save all incarnations of files so
      you can restore the whole directory tree. Then you should specify
      no-compress mode.

      C: YES|NO

      When running in compress mode up to 800 different multilinked files
      can be handled before the program switches to no_compress mode.
      For each new multilinked file encountered after that a warning is
      issued.

   -  Date mask facility so one may save only those files changed after
      a given date.

      Syntax:

      A: <date> [. <hour> ]

      <date> ::= yymmdd (y= year, m= month, d=day)

      <hour> ::= hhmm   (h= hour, m=minute)

      Default: 000301.0000 (March 1st, 1900)

      Example:

      MT_SAVE T:JAS D:@**USERS.D*JAS.D L:2 A:840101.1315


Changes:
--------

   >> V0303 <<

      Off. version of CONV_TIME used with slightly modified I/F.

   >> V0302 <<

      The tape is rewinded before the operator is asked to mount the
      next tape because the program cannot survive a YES to the
      'READY?' question if a tape has not indeed been mounted.

      The error message '*****ERROR AT TAPE INITIALIZATION' has been
      converted to '*****TAPE WRITE PROTECTED'.
      (PR86291)

      Linked with version 2.4 of MTC.L to survive spurious interrupts.
      (PR86369)

   >> V0301 << of MT_SAVE

      Directories at max. nesting level are now skipped.

      Linked with version 2.3 of MTC.L to be able to survive the occational
      loss of an interrupt from MT Controller.

   >> V0202 <<
      Linked with version 2.2 of MTC.L which clears interrupts
      (MX PR 18).

Errors corrected:
-----------------

   >> V0303 <<
      May be used with input from disk (Answer to 'Want to load more
      tapes' ).This problem is raised by Tulsa in FAX/KEJ/1317.

Reported errors, not corrected:
