First information about the binary distribution of VMS Zip 2.3
--------------------------------------------------------------
This archive comes in different variations:
"zip22x-vms-<cpu-compiler>-{obj|exe}.zip",
where <cpu-compiler> is "axp", "vax-decc", or "vax-vaxc", depending on
the environment used for creating the binaries.
...-obj.zip denotes object library distributions which require
a link step on the local machine.
...-exe.zip denotes "ready-to-run" executable distributions, that do
not require additional work but do not run on VMS versions which are
older than the system used for building the executables.
Contents of the "vms" executables archives for Zip 2.3:
a) common files (documentation etc.):
00binary.vms this file
00readme.txt additional VMS info about compiling Zip
readme what Zip is; general information
changes list of changes against the previous official version
algorith.txt description of the deflation algorithm
infozip.who list of contributors to the "portable Zip" project
manual Zip manual page, human-readable format
whatsnew list of important changes and new features
where pointer to Zip/UnZip support archives
zip.hlp VMS help module, for Zip's default command interface
zip_cli.hlp VMS help module, for Zip's VMSCLI command interface
b) object library distributions:
link_zip.com command procedure for the linking step
vms/ auxiliary directory, required for link step
zip.<cpu_compiler>_olb object library for Zip (both command interfaces)
zipcli.<cpu_compiler>_olb additional object library (Zip CLI interface)
zipcloak.<cpu_compiler>_obj main object file for ZipCloak
zipnote.<cpu_compiler>_obj main object file for ZipNote
zipsplit.<cpu_compiler>_obj main object file for ZipSplit
ziputils.<cpu_compiler>_olb object library for the Zip Utilities
c) executable distributions:
zip.exe Zip executable, default (UNIX style) command interface
zipcloak.exe Utility for encrypting and decrypting zip archives
zipnote.exe Utility for editing entry names and comments
zipsplit.exe Utility for splitting large zip archives
zip_cli.exe Zip executable, VMSCLI command interface
In case you decided to fetch the object library distribution, you
have to link the executables on your local site. This requires
installed runtime support for the C runtime library, which may not be
present on older VAX systems (prior to VMS 6).
To create the executables, just invoke the "link_zip.com" command procedure.
This will generate all executables (both zip with UNIX style command syntax
and zip_cli with VMSCLI command interface), but note that the executable's
extension is ".<cpu_compiler>_exe"!
In case your are on a VAX and your current working directory carries
both the DECC and the VAXC object distributions, you have to specify
either "VAXC" or "DECC" to tell link_zip.com which binaries you want
to build.
Additionally, link_zip.com defines foreign commands for the just created
executables, so you can test them straight ahead.
If you want to use the default (UNIX like) command interface, you can
proceed straight ahead after unpacking the distribution.
When you rather prefer to use the VMSCLI interface, you have to specify
the option "VMSCLI" (or just "CLI") to the command starting link_zip.com.
The executables (object libraries) in this archive have been compiled
with the following options enabled:
* VMS_PK_EXTRA (this is the default option)
* [decription support]
The environment used for compilation was:
a) On Alpha AXP : OpenVMS(AXP) 6.2; DEC C V 5.6-003
b1) On VAX : OpenVMS(VAX) 6.2; DEC C V 4.0
b2) alternatively VAX C V 3.2
One final note:
The binary files of the distribution have been archived with "saving all VMS
attributes" enabled. Please do not repack the binary part of the archives on
a non-VMS system, to prevent corruption of the files.
