Wimp_SetIconState only changes the icon flags. The validation string 
is held in a buffer in your application's workspace. You can find its 
address via Wimp_GetIconState. You can modify it directly in memory 
(but beware of exceeding its allocated size), then force an icon 
redraw using a dummy Wimp_SetIconState call (passing 0 for EOR/BIC).

The validation string is a very basic Wimp feature. It might make 
sense to first read a book or tutorial. That will allow you to proceed 
more quickly than asking here for every little step. For instance, the 
"Beginner's Guide to WIMP programming" as published in Foundation 
RISCWorld is available online on the APDL site.
