This is an example of some of the features of a Value Set Control.  The code
works on the OS/2 2.0 6.167 Beta release.  It should be buildable for any
release that contains the Value Set control.  The code was written using the
IBM C Set 2 compiler.  Notice that the code was compiled with full debug on. 
It can be rebuilt without debug to make it smaller.

From a user perspective, the value set contains a set of icons.  If you select
any of the icons, a beep will occur.  If you double click on an icon, it will
be transfered to the other value set if the equivalent spot is open.  You can
drag an icon to any spot.  

Impressive huh? <grin>  

In order to do all this, one learns about many of the messages that move
between the control and its owner. It is these messages that this example is
all about.

You may make as many copies of this example as you wish, and you may distribute
them where ever you wish.  You may not charge for them.  The icons were not
created by me but downloaded from CIS in the windows forums.  They were then
converted to OS/2 via CVTICON.  I only have full rights to the code example.
