    MENU SET STATE is unfortunately broken... Until the next update becomes available, you can use the EnableMenuItem() API instead.

        I take it you have not downloaded and installed WIN32.HLP? (8Mb download from http://www.powerbasic.com/files/pub/mstools/win32.zip )

        Anyway, to use EnableMenuItem(), you'll need to #INCLUDE "WIN32API.INC" into your app, then the API syntax is thus:
        Code:
        Result& = EnableMenuItem(hMenu&, MenuItem&, MenuItemFlags&)
        where:
        Code:
        hMenu&         = the menu handle
        MenuItem&      = the item's ID number
        MenuItemFlags& = the desired menu item state (%MF_GRAYED, etc).
        Result&        = the previous state, if the API call was successful or 
                         -1 if an error occurred
        I hope this helps!

          C'mon Lance, if you're gonna go that far to help someone with an acknowledged "broken" (amazing how that other "b" word remains a four-letter word) function, why not take the bus to the end of the line?

          MenuItem& = the item's ID number
          MenuItemFlags& = the desired menu item state (%MF_GRAYED, etc).
          MenuItemFlags& may be written 'syntactically' as:

          Code:
          MenuItemFlags& = ({%MF_BYPOSITION | %MF_BYCOMMAND}) OR ({%MF_GRAYED|%MF_ENABLED|%MF_DISABLED})

          When MenuItemFlags includes %MF_BYPOSITION, Menuitem& is the zero-based index of the item on the menu to affect.
          When MenuItemFlags includes %MF_BYCOMMAND, MenuItem& is the "control id" associated with the menu item.

          MCM
