Re: How do you call a process

call_proc() and call_func() use id's provided by routine_id(), so to make it
work, you'd need this:

    atom myID
        myID = routine_id("onClick_MenuGetRec")
        call_proc( myID, { 0, 0, {}} )    -- self = 0, even = 0, parms = {}

or simply this:

    call_proc( routine_id("onClick_MenuGetRec"), {0, 0, {}} )

With Win32Lib, however, I recommend using invokeHandler() to call the event
handlers for your controls. call_proc() and call_func() are used internally
by invokeHandler(), and if anyone ever looks at your code, invokeHandler()
will give them a better understanding of what you're doing.
