To explain this .bat script: you have downloaded a few .ZIP files from
some site, and need to unzip each and run them -- to test whether the
programs do what you hope and are worth keeping. Usually, this means
creating a handful of subdirectories, and unzipping one .ZIP into each.

This batch program does that task for you: it will create a subdirectory
[within the current directory] named according to each of the .ZIP files
specified, and unzip each file into its own directory. For example, a
file named DC106F.ZIP will be unzipped into a subdirectory named DC106F

The .ZIP file extension can be omitted, and wildcards and drive letters
are allowed, though I have written it so that the drive letter need be
specified only once, and is assumed to apply to all following filenames.

Examples:  UNZIP2D  A:*.*

           UNZIP2D  A:DC*.*  LIST*.*  BATMNU21  READ131  SETEN*.*


UNZIP2D.BAT:
-----------
@echo off
if "%1" == "+" goto T
if "%1%2" == "" echo  usage:  unzip2d  a:*.*  b:file2.zip  ...
set d=
for %%f in (%1 %2 %3 %4 %5 %6 %7 %8 %9) do call c:unzip2d + %%f
goto X

:T
for %%i in (/%2) do set r=%%i
set c=%r%
for %%i in (/%2) do if not %%i==%r% set c=%%i
if %r% == %2 set r=.zip
if %c% == . goto W
if %c% == : set d=%3:
if not %c% == : set r=%r% %3%c%
call c:unzip2d + %r%
goto X

:W
if exist %d%%3.%r% mkdir %3
pkunzip %d%%3.%r% %3
:X

I have used this with DOS 5, but cannot say it will work for all versions.
It is a peculiarity with DOS that where you use a wildcard in the filename
then you must also specify the file extension (either as .zip or just .*).
Of course, the pkunzip (or equivalent) executable needs to be in your PATH.
