ZipV - Bit Masons Zip Viewer 1.21
Copyright 1990 by Gordon Haff and Bit Masons Consulting.
All rights reserved.
Command: ZV
Purpose: Provides a scrollable environment for selecting
files contained within a ZIP file and viewing or
extracting their contents
Syntax: ZV [d:][\path\]filename.ZIP
Commands: <Enter> views files
<Space> or <e> extracts files
Prereqs: 100% IBM Compatible PC running DOS 2.1 or higher
Archive Name: ZIPV120.ZIP
Associated Programs:
In its default configuration, ZV REQUIRES Vern Buerg's
LIST file viewing program and Phil Katz's PKUNZIP
program. LIST and PKUNZIP are Shareware and require
separate registration with their authors.
While ZV can be operated from the DOS command line
using the format described above, it is most
conveniently called as a user-defined shell command
(or SmartViewer in DF 4.0 and later) from within the
author's Directory Freedom (DF) program.
Other: Your COMSPEC variable must be set. See Section 2.1.

TECHNICAL SUPPORT
Since this program is a freebie, unlike the shareware programs
for which I request a registration fee, I'm not going to make any
guarantees here with respect to bug fixes or other technical
support. Having said that, I do like my programs to be as
bug-free as possible, so feel free to report any problems which
you run across.
Contact via:
Channel 1 BBS (617) 354-8873
Compuserve User ID# 72561,2637 (See Note 1)
InterNet/ARPANET 72561.2637@compuserve.com
U.S. Mail 3205 Windsor Ridge Dr.
Westboro MA 01581
Telephone (508) 898-3321 (after 6pm
Eastern time)
The above are roughly in order of preference (i.e. how quickly
I'm likely to see your message and be able to respond). I check
Channel One almost daily and the other electronic services at
least weekly in most cases. In addition, I monitor the Interlink
and the PCRelay Shareware relays through Channel One.
Note 1:
When contacting me via Compuserve, please use the Easyplex mail
system since I do not regularly monitor any of the IBM SIG
message bases.

1.0 Why and Whence ZV?
-----------------------
The main reason that I wrote ZV is the following: I have a
shareware file management program called Directory Freedom which
is small and fast in spite of having more wonderful and exciting
features than I could possibly describe here (Plug #1). Yet,
there was still one thing which I continually ended up having to
exit DF to do -- namely, to view the contents of files contained
within ZIP files.
This annoyed me.
I looked high and low for a program which I could call with DF's
nifty user-defined shell function (Plug #2), but nothing did
exactly what I needed. So out came the assembler and, a week or
so later, out popped ZV,
So.... armed with ZV, DF can now perform most of the major
archiving and de-archiving functions that people who deal
primarily with Phil Katz's ZIP format need. (The next major rev
of DF will have the capability to archive files.) For the fancy
stuff (such as selective de-archiving), you'll still need a
program like ARCMASTER or SHEZ, but DF will be able to handle all
the everyday stuff.

2.0 How does it Work?
-------------------------
I'm glad you asked that question. It works incredibly well.
Oh.. HOW does it work. Well,
