DEARC/CMD version 3.0 is an archive extraction utility compat-
ible with ARC31, ARC4 and MSDOS ARC and PAK utilities.  It
requires a 48k Model I, III, or 64k Model 4.  If you have
problems with DEARC, please send the bug report with as much
technical information as you can to me at the below address
(registration not required to report bugs, but it would be
nice) or to my BBS:
      West End BBS, (914)858-8722, 300/1200 baud.
DEARC is written entirely in assembly language and takes up
less than 7k of disk space.  Enhancements over version 2.0
include support for Models 1, 3, 4 in one program, support for
the information and control items in ARC version 6, support for
crushed and distilled members made by PAK.EXE, revamping of the
partspec routine so you can specify the partspec using charac-
ters not legal for TRS80 filenames, multiple partspecs on the
command line, an elapsed time indication on program exit, query
before extract on each member, setting of LRL of extracted mem-
bers, and testing of archives.
  DEARC is distributed as shareware and may be freely copied as
long as it is unaltered and this file accompanies it.  If you
find it useful, you are asked to send $10 to:

DEARC version 3.0 will extract or test Stored, Packed,
Squeezed, crunched, Crunched, Squashed, Crushed, and Distilled
members.  It will extract to a file, the display, or a printer.

Usage:
DEARC filespec (DIR)
DEARC filespec (DIR,PRINT)
DEARC filespec
DEARC filespec partspec (parm,parm,...)
DEARC filespec partspec
filespec   is the archive filespec, default extension is /ARC
partspec   is an optional filter to choose members to extract
           or exclude

Allowable parameters:
DIR     displays a directory of files in the archive
LIST    routes extracted files to the display
PRINT   sends display output to the printer as well
GARBLE= "password" specifies a decryption key.
N       specifies filtering of CR-LF to CR
QUERY=  N disables queries before overwriting existing files
TEST    tests archive integrity
LRL     sets logical record length for extracted files (does
        not affect pre-existing files' LRL)
Abbr: D=DIR, L=LIST, P=PRINT, G=GARBLE, Q=QUERY

DEARC TRSLNK19 (DIR) displays the directory of TRSLNK19/ARC
    (or TRSLNK19/PAK if TRSLNK19/ARC does not exist) on the
    screen.
DEARC RAMSOFT/ARC (D,P) sends the directory of RAMSOFT/ARC to
    the printer.
DEARC TEST extracts every member of archive TEST/ARC (or
    TEST/PAK) to the first available drive.
DEARC CPROGS :1 extracts all members of CPROGS/ARC (or
    CPROGS/PAK) to drive 1.
DEARC MISC /TXT(L,P,N) sends all members of MISC/ARC (MISC/PAK)
    with extension TXT to the printer, filtering carriage
    return-line feed to carriage return.
DEARC MISC -README:1 extracts all members of MISC/ARC
    (MISC/PAK) except those whose filenames start with README
    to drive 1.
DEARC CODED :2(QUERY=NO,GARBLE="GARBAGE") will extract all
    members of CODED/ARC to drive 2, overwriting any existing
    files with matching filenames and using GARBAGE is a
    decryption key.
DEARC TRSLNK28/ARC .DOC:1 .ARC:2 will extract all members of
    TRSLNK28/ARC with extensions of /DOC to drive 1 and all
    members with extensions of /ARC to drive 2.
DEARC TRSLNK29 (TEST) tests the integrity of TRSLNK29/ARC
    (TRSLNK29/PAK)
DEARC DEEPSKY :1(LRL=135) extracts all members of DEEPSKY/ARC
    (DEEPSKY/PAK) to drive :1 using an LRL of 135
<BREAK> will end execution of DEARC at any point, and <SHIFT>-@
    will pause the output if the DIR or LIST parameters are
    used.

              ------------------------

Also included in this package are ARC2CMD/CMD, ARCL31/CMD, and
ARCL4/CMD.

              ------------------------

ARC2CMD/CMD version 1.2 is a self-extracting archive utility
which works in the same environments that DEARC version 3.0
does.  It is shareware and must be registered before it is used
to distribute a commercial program.  Shareware authors are
requested to register it.  It may be freely used to distribute
freeware and public domain programs.  Usage is:

ARC2CMD [source [destination]].

If the source and/or the destination filespecs are left out,
ARC2CMD will prompt for them.  Default filespecs are /ARC for
source and /CMD for destination.  The usage of the resulting
file is:

filespec [:d]

where filespec is the name of the self-extracting archive and
:d is the output drive.  If the output drive is not specified
on the command line then it is prompted for during execution.
The extraction module of ARC2CMD version 1.2 can extract all
compression modes supported by DEARC version 3.0.

Technical info: bytes 2-5 (relative from 0) of the /CMD file
contain a 32-bit integer in low-high format indicating the
offset to the start of the archive.  Bytes 6-17 contain the
original name of the archive in a null terminated string. Bytes
0-1 are a standard TRSDOS comment loader block header (1FH
followed by the length of the block, in this case 10H).

              ------------------------

ARCL4/CMD is an archive viewer which lists the directory of an
archive to the screen.  It runs under TRSDOS/LSDOS 6.x in the
library overlay region (2600h-3000h), thus may be used from
within BASIC and many communications packages.  To use it from
BASIC, use SYSTEM"RUN ARCL4 archive".

ARCL31/CMD is identical to ARCL4/CMD except that it runs under
most Model 1/3 DOSes and loads starting at 5200h.  To use it
from LDOS BASIC, use CMD"ARCL4 archive".  Consult your manual
to see if your basic allows execution of non-system commands
from within it.
