Subject: LBR Files and Compression

   Lindsay Haisley's list of tools for dealing with LBR archives containing
compressed files omitted my favorite: LBREXT.  This program will extract
member files from libraries and optionally uncompress them from squeezed
(*.?q?), crunched (*.?z?), and LZH encoded (*.?y?) format.  LBREXT is a full
Z-System program that will work perfectly under standard CP/M as well to the
extent possible.  The syntax is

        LBREXT lbrfile[.LBR] member1[,member2,...] [/option]

The LBR file name can be given with or without the LBR extension.  One may
give a single member file specification (which may be 'ambiguous', that is,
contain '?' or '*') or a number of such specifications separated by commas. 
The option '/U' specifies that any matching compressed member files are to
be uncompressed as they are extracted.  I believe the '/O' option specifies
the the extracted file(s) should overwrite any that already exist.

   Lindsay was nice enough to mention my Z-Node as a good source for these
files.  The Z-Node concentrates on files that run specifically under Z-
System.  I operate a second BBS (running on DOS hardware with PCBoard, two
phone lines, and high-speed modems) at 617-965-7046.  That BBS supports
general CP/M and MS-DOS and has a directory dedicated to support of
archiving and compression.  At the moment, the main phone number has a
v.32bis modem.  If that line is busy, the connection hunts to the second
line (617-965-7785) which has a USRobotics Courier HST modem.  However, I am
about to reverse these lines so that people with v.32bis modems can
guarantee connection to my v.32bis modem by calling the second number
directly.  That switch may have occurred by the time you read this message.
