This can be done in a couple of ways depending upon what information you
have available.  The basic flow is:
 
 -get a window handle to the menu
 -get the id of the menuitem
 -send a WM_SETITEMTEXT to the menu with the id and the text
 
If you already know the id of the menu item it is fairly easy - use the
basic steps outlined above.  If you do not know the id then you must use
the MM_QUERYITEMCOUNT message and then successive WM_ITEMIDFROMPOSITION 
to get the item id, then MM_QUERYITEMTEXT to get the text.  When you've
found the menu item you want to change (by comparing the menu item text 
to a known value) you can set it by using a MM_SETITEMTEXT message.
 
This all sounds terribly complicated but isn't really too horrible.  
There may be 'helpers' for this task but it is fairly straightforward to 
write a small generic routine to emulate the Windows equivalent.  Browse 
through the PMWIN.H and see if there is something hidden in there that 
accomplishes this.
 
Hope this helps.
