         Differences with earlier versions of PocketD.


Version 1.00  Jul91: The first Shareware release version
Version 1.34  Dec91: First PsL version

Version 1.48  Dec91:

    .Many  improvements,  including  Six new  template  parameters,
     improved  colour support, support for ZOO, LZH, ARJ, ARC,  PKA
     and  PAK  as  well  as  ZIP files, dual  execution  templates,
     "typed" characters allowed in filenames (e.g =D digit).

    .Archive bug fix (over v1.34)

Version 1.56  Jan92:

    .Addition of /s "safe" switch to copy ( Previous /s "show skip"
     is now renamed /g). This tests whether the destination file is
     larger or much smaller before copying.

    .User can now preview the contents of each file before deciding
     to copy it.

    .HEX  file  view  includes  the  file  offset  address    in  the
     left-hand margin (as LIST).

Version 1.59  Feb92:

    .The  registered version now comes with a professional type-set
     pocket-sized  manual.    This  results  in a small  increase  in
     registration  cost,  but not enough  to cover the cost of  the
     manual,  and so this is really a price drop. The pressure from
     users to do this was just too great!

    .The addition of  an option to delete subdirs by using the form
     "name /zd" as a convenient alternative to  "name\ /Szz".

    .Copy  now  reverts to    normal copying after a "safety"  query.
     /s "safety"  now also pauses on the "MUCH OLDER" condition  as
     well  as  the    size  check.  The "A" key input (copy  all)  in
     response  to  a copy  query will now override    further  safety
     checks. "N" now does not stop copy, but just skips the current
     file  (bug  fix). Additional  code has been added  to    improve
     PocketD's  decision making for whether the destination name is
     an implied directory or file name.

    .Matching  files  are checked to  see if they are  dated  after
     system  time, and reported if so. This traps situations  where
     the  MS-DOS date has not incremented at midnight, and so files
     may  have been saved with the wrong date, and consequently may
     not be backed up or may not be picked up by MAKE. The check is
     inhibited  by    the /.w  "warnings off" option. This  condition
     will  cause copy to switch to query mode (unless inhibited  by
     /.w).

    .Copy/move   will  "overwrite  and  then  truncate"  when   the
     destination  file  already  exists,  rather than  "delete  and
     create".  This  allows PocketD  to take advantage of  enhanced
     file  permissions  provided by  networked PC systems  such  as
     NOVELL,  which allows    separate write and delete  permissions.
     This  would  allow  users  to    add and overwrite  files  to  a
     restricted  directory, but not delete. This capability is  not
     supported by any of DOS's copying facilities.

    .The  on-line viewing of files as HEX or TEXT will now    display
     all possible characters above 7F in the IBM character set, not
     just the line-draw subset.

    .The  on-line manuals are  now encrypted (sorry!). It was  just
     too  easy for users to  turn these into printed manuals,  thus
     reducing the incentive for registration.

    .Extraction  of  names    from  PKZIP archives now  includes  and
     option  to obtain pathnames and names (using /Z[zp] instead of
     /Z).  This  allows  PocketD  to  be  used  for  the  automatic
     extraction of both files and files with pathnames.


Version 1.64  Apr92:

    .Improved optimisation has limited the increase in code size to
     only 150 bytes (despite many new added features).

    .D   now  supports  an    additional  alternative  "display-only"
     template  when  running  a  series  of commands from  D.  This
     substantially    improves  D's  capacity for creating  utilities
     which require user interaction. The user can be presented with
     an  intelligible  question rather  than a command sequence  to
     run.  This  makes utilities  such as tree-browsing or    archive
     viewing   much   easier   to  use.  The   template   form   is
     [exec..][?query],  where the "?" after "[" indicates that  the
     template is for display only. Since D allows 2 templates, then
     this  would allow the user to define 2 execution and 2 display
     templates within a single command.

    .To  help NOVELL users, copy now supports sub-options /w  "wait
     on  fail to open" and /i  "ignore file on fail to open".  This
     will allow D to wait for or skip files already opened by other
     network  users. If /i is used with /o (optimise), then D  will
     copy  all the files it can and then cycle through the files it
     could not open the first time, until all are copied.

    .The  size  of the /s  copy safety window can now  be  directly
     controlled,  allowing the user to define the range of relative
     file  sizes that D can overwrite without first querying.  e.g.
     /cs.40-105  would  allow overwrite  of files that fell in  the
     range 40%-105% of the source file size without querying.

    .The /R run option now has the sub-option "." which causes D to
     exit after executing a single template. Errorlevel now returns
     the  number  of templates  executed when used with /R,  rather
     than  lines output. This allows the user to perform additional
     testing within BAT files.

    .D  now converts "/" in pathnames found in ZIP archives to  "\"
     to allow processing by DOS.

    .The  template    parameter  $#  (get  next number) and  $=  (get
     previous  number) have been replaced by $# which simply  gives
     the  current file/dir number. This is more satisfactory as  it
     allows  the user to step the number in both directions,  while
     still    guaranteeing that each file/dir referenced has a unique
     number.

    .New  template    parameters  $.Y,  $.y,    $.m and  $.d,  allowing
     separation  of the date parameter  $d into full year, 2  digit
     year, month and day.

    .Template  numeric parameters (excepting $U, $S and $s) can now
     be  padded  by  leading  zeros  as an alternative  to    leading
     spaces. e.g. $03F would give "004" instead of "  4" for $3F or
     "4" for $F.

    ./q  and /l options now have a sub-option to directly view  the
     first file selected rather than prompting before viewing. This
     is  specified    by /q. or /l.  instead of the normal /q  or  /l
     usage.

    .The  template parameter $a will bow default to give the single
     attribute  character \,r,h or s. Users who previously used  $f
     to  give full attributes will now need to add the /f option to
     the command line.

    .The  command  D A: /c FRED  will now behave as D A:*.* /c FRED
     copying  from    drive A: to  subdir FRED, rather than  to  file
     FRED.    Also "=x" "typed" wildcard  is now treated as a  normal
     wildcard when copying files. This is obviously preferable!

    .Bug  fix  from v1.59 which  caused D to fail to  automatically
     inhibit  prompting  when  re-directing  output  to a  file  or
     printer.

    .D  no    longer displays  the misleading "Skipped" message  when
     toggling between execution templates.

    .Bug fix of D failure if last option in D_OPT is copy or string
     sub-option and D_COL is also set.

    .Bug fix of failure when too many files found during copy.

     Version 1.66  May92:

    .File  sorting    now uses  quicksort instead of selection  sort,
     resulting in an increase in sorting speed of 6 fold (80 files)
     and  11  fold (600 files).  This gives a total  net  execution
     speed improvement of about 1.2 and 2.0 fold.

    .Further  optimisation has been made in the use of filespecs on
     the  command-line that do not contain wildcards. This    greatly
     benefits  matching  individual  names    in  large  directories,
     giving  speed-ups  of 1.2  to 2.0 fold. This  is  particularly
     useful   when    using  D  as  a  MAKE  tool,  or  for    testing
     date-stamped files for backup purposes.

    .Building of large file lists are now about twice as fast. Also
     the maximum file list size that D.EXE can create has increased
     from about 1200 to 1500 (still 10,000 for DL.EXE).

    .Extra template parameter $c added to give current date.

    .Extra    copy option "f" to inhibit final summary. /h will  also
     inhibit this and the "touched files" summary.

    .Extra /qq sub-option to inhibit query if single matching name.
     This is useful when used with /R (run).
