   That's well before my time.  The oldest UnZip source kit
I've found here is 5.51, and it seems to have it:

ALP $ r SYS$SYSDEVICE:[UTILITY.SOURCE.ZIP.UNZIP551]UNZIP.AXP_EXE
UnZip 5.51 of 22 May 2004, by Info-ZIP.  For more details see: unzip -v.

Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]
  Default action is to extract files in list, except those in xlist, to exdir;
  file[.zip] may be a wildcard.  "-Z" => ZipInfo mode (`unzip "-Z"' for usage).
=> define foreign command symbol in LOGIN.COM:  $ unzip :== $dev:[dir]unzip.exe
[...]

   My only significant contribution in this region was adding
a space, to avoid confusing the victims with non-zero
allocation classes, to wit:

=> Define foreign command symbol in LOGIN.COM: unzip == "$ dev:[dir]unzip.exe"

(If your "dev" looks like, say, "$1$DIA0", then you might not
notice that the "$" in "$dev" is not your "$".)

   If you like the old bugs, and don't want the new features,
then you can use anything you want.  (Personally, I'd use
something newer, if for no other reason, then for the faster
file I/O.  It seems foolish to me, but I wouldn't dream of
twisting your arm.)
