The CGFWC!10.zip archive contains .wcx files compiled with wcCode
   4.01 as well as 4.10.  To use CGFWC! with a 4.01 system do the
   following:

    1.  Move the files GROUP2.WCX and GROUPIX.WCX out of the directory
        you have created for the CGFWC! files.

    2.  Rename 401_IX.WCX as GROUPIX.WCX

    3.  Rename 401_2.WCX as GROUP2.WCX

     That'll do it.  Set up and run as per the GROUPS.DOC file.
     The only difference in the 4.01 and 4.10 versions is the addition
     of the updatescreen function in 4.10.  The writes to the screen
     in the 4.10 version are a little smoother as a result.
