8. Beta release 20.November.1998
---------------------------------
1) CHG: {zip/unzip) switch to latest source level
zip 2.3h beta and unzip 5.4 final release
2) ADD: {zip} Zip finds "namelocked" files also, if switch "-S"
is set.
3) FIX: {unzip} Function isZipfile() fails if the zip archive
has a comment.
4) CHG: {zip} added some small speed improvements to pattern matching and
isZipFile() function.
5) FIX: {unzip} Display of comments is fixed.
UzpMessagePrnt() is replaced by MacMessagePrnt(). I do not care

-VM/CMS Extra Field:
==================
The following is the layout of the file-attributes extra block for
unzip-6.0/proginfo/fileinfo.cms view on Meta::CPAN
fopen() and freopen() parameters
recfm
CMS supports only two RECFMs, V and F. [note that MVS supports
27(!) different RECFMs.] If you do not specify the RECFM for a
file, C/370 determines whether is is in fixed or variable format.
lrecl and blksize
For files in fixed format, CMS allows records to be read and
written in blocks. To have a fixed format CMS file treated as a
fixed blocked CMS file, you can open the file with recfm=fb and
specify the lrecl and blksize. If you do not specify a recfm on
the open, the blksize can be a multiple of the lrecl, and the
file is treated as if it were blocked.
For files in variable format, the CMS LRECL is different from the
LRECL for the record model. In the record model, the LRECL is
equal to the data length plus 4 bytes (for the record descriptor
word), and the BLKSIZE is equal to the LRECL plus 4 bytes (for
the block descriptor word). In CMS, BDWs and RDWs do not exist,
but because CMS follows the record model, you must still account
for them. When you specify V, you must still allocate the record
descriptor word and block descriptor word. That is, if you want
a maximum of n bytes per record, you must specify a minimum LRECL

VMSV5.5-2 is too old. V7.3 is new enough. Anyone with more precise
information is invited to contribute it.
Users who find other parameter sets more beneficial, or who find
particular problems with this set are welcome to comment.
In this version, as in previous versions, when UnZip expands a -V
archive, it allocates the entire extent of a data file before writing
any of its data. In some previous versions, this could cause the
destination disk to be locked for a considerable time (minutes), if
highwater marking was enabled on that disk. Now, the FAB SQO
("sequential access only") flag (or equivalent) is set, which prevents
this troublesome disk locking.
In some previous versions, when UnZip expanded a non-V archive, it
did no pre-allocation, and used the default extension quantity. This
could slow file creation significantly for large files. Now, space for
extracted files is pre-allocated, and the same SQO ("sequential access
only") flag is set, as with a -V archive.
