Notes:

You must install the Java JRE to use this program.
See http://mindprod.com/jgloss/jgloss/jre.html

This program can only be used from the command prompt, (or via an command
line style icon shortcut) e.g. under Windows command.exe or JPSoft
tcmd.exe, formerly called the DOS box. Just clicking the programs in a
directory listing will not do anything useful. Just typing the program
names at the command prompt will not either.

This program requires a manual install! See below.

This program works with vanilla text files, (e.g. ASCII files or UTF-8
Unicode files). You will need a text editor to create and view them, not a word
processor. e.g. notepad, Visual Slick Edit or other suitable text editor
http://mindprod.com/jgloss/editor.html. You must use a monospaced font
http://mindprod.com/jgloss/monospacedfonts.html (aka fixed pitch, aka
programmer font) to view your files, or they won't look properly aligned.

I put out an avalanche of free software into the world, and submit PAD
files to hundreds of distribution sites, but I rarely hear back from
anyone.  What's happening?  Does it all just work fine?  It is so
complicated nobody can figure out how to use it and they give up on it?
It is it useful?  Since everyone has the source, do people just fix the
programs to their liking themselves?  Did you have trouble installing?  Do
I presume you know too much?  I would be happy to hear from you about your
experiences, positive or negative and your requests for improvements.  A
one-line email to roedy@mindprod.com would be great.

===> Free <===
Full source included.
You may even include the source code, modified or unmodified
in free/commercial open source/proprietary programs that you write and distribute.
May be used freely for any purpose but military.
For more details on this restriction, see
http://mindprod.com/contact/nonmil.html
If you include any Canadian Mind Products code in your own applications,
your app too must be labelled non-military use only.
http://mindprod.com/contact/nonmil.html
All Java jars and source code are included. If you need the class files or Javadoc, you will have to build them yourself. To streamline the zip downloads, class files and Javadoc have been removed.

----

Prerequisites:

This program runs under any OS that supports Java,
(e.g.W2K/XP/W2003/Vista/W2008/W7-32/W7-64/W8-32/W8-64/Linux/LinuxARM/LinuxX86
/LinuxX64/Ubuntu/Solaris/SolarisSPARC/SolarisSPARC64/SolarisX86/SolarisX64/OSX/AIX...)
so long as you have
<><> Java version 1.8 <><> or later installed (32-bit or 64-bit Java).
See http://mindprod.com/jgloss/installingjava.html for details.

----

Installing on a PC:

Download source and compiled jar files to run on your own machine as an application.
First install a recent Java JDK or JVM.
See http://mindprod.com/jgloss/installingjava.html.
To install, extract the zip download with WinZip
(or similar unzip utility) into any directory you please,
often J:\ --  ticking off the <span class="click">use folder names</span> option.
To run as an application, type:
java.exe %JAVA_OPTIONS -ea -jar J:\com\mindprod\which\which.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Installing on a MacIntosh:

Use Safari to download source and compiled jar files to run on your own machine as an application.
Safari will automatically unpack the zip into ~/Downloads (version 10.5)
[or on the Desktop (version 10.4 and earlier)].
First install a recent Java JDK or JVM.
See http://mindprod.com/jgloss/installingjava.html.
You may optionally move the download tree to a permanent home.
I don't have a MacIntosh, just a PC, so I can't test my Java programs for Mac compatibility.
In theory they should work without problems, but in practice that does not always happen.
If you have problems please, let me know, preferably with screenshots and complete verbatim error messages.
To run as an application, without parameters, just double click the jar file.

To run as an application with parameters, in bash shell type:
open Terminal.app
cd ~/Desktop
java.exe -ea -jar com/mindprod/which/which.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Rebuilding:

The zip already contains the necessary jar files, so unless you modify
the program, there is no need to recompile the source or rebuild the jar.
Configure.java basedir="E:/" in rebuild.xml to the drive where your files are.
Use ANT and rebuild.xml, not build.xml, to recompile and recreate the jar.

----

Use:

Which is a Java utility for Windows that searches the path and tells where
it finds a given exe or dll.  It further tells you what type of exe/dll it
is, i.e.  DOS 16-bit, Windows 16-bit, Windows 32-bit, Windows AMD 64-bit,
Windows Itanium 64-bit, Jet 32-bit or Jet 32-bit that is out of date, and
needs to be recompiled for the latest runtime.
If you use the Jet version you use by typing:
Which.exe  someprog.exe
or
Which.exe somedll.dll
on the comand line.
If you have *.jar set up as an executable extension you can type
which.jar someprog.exe
Otherwise you will have to type the verbose:
java.exe -jar which.jar someprog.exe
It sets the retcode depending on what it found:
retcode  Type
 8       DOS 16-bit
16       Windows 16-bit
32       Windows 32-bit
33       Windows 32-bit Jet
34       Windows 32-bit Jet, out of date
64       Windows AMD 64-bit
65       Windows AMD 64-bit Jet
66       Windows AMD 64-bit Jet, out of date
70       Itanium 64-bit
90       an unknown type
91       unable to find/read the file
99       syntax error
You may have other utilities called Which. Make sure you are usingh this one.
WHAT IS JET?
JET is an AOT Ahead Of Time Java Compiler that converts Java class files
into ordinary *.exe files that look like conventional C/C++ executables to
the end user.  They load and execute faster than ordinary Java jar files.
They require a DLL run time to work.  WHICH tells you which of your
executables are JET-complied which require the JET runtime and which do
not.  WHICH warns you when you have JET-compiled executables that would
benefit from recompiling for the latest runtime.  You can read more about
JET at http://mindprod.com/jgloss/jet.html
Beware.  You may also have a copy of JPSoft Which or Cygwin Which on your
computer.  You may think you are using CMP Which, but you could be using
one of these.
ICON
Why the clothesline icon?  The clothes represent the various directories hanging off the path.
