xCYCLER  L T W H Title Variable 

This is a cycler at L, T of Width, Height. It's value will be placed 
in Variable. The Title (if any) will be placed to the left.

You MUST tell a cycler what fields you want it to have, i.e. what will
be written on it's face every time the user clicks it.

You do this by attaching to it CSTR (Cycler-String) commands, as follows :

 xCYCLER  L T W H Title Variable 
 CSTR  Title Value
 CSTR  Title Value
 .. etc .., up to 12 CSTRs

The Title of the CSTR is what will be placed on the face of the button
and the value is what will go into the Variable.

The 1st field in cyclers & radio buttons is No 0.
