Int 15 Fn 12  - Topview - Send Message - "apply" - Write Panel To Window   [Q]

   AH = 12h
   BX = 0400h
   STACK: DWORD handle of panel object
          DWORD window's handle (or 0 for current task's window)
          DWORD length of panel name
          DWORD pointer to panel name

Return: STACK: DWORD handle of window which was used
          DWORD handle of keyboard or 0

Notes: status of APPLY may be checked with STATUS message
   panel MUST have the following format
     first byte must be 1Bh (i.e. must start with a stream)
     first opcode in stream must be E5h
       single byte arg of opcode is interpreted thus:
         bits 7,6  11 means create new window
           10 means create new field table for existing window
           01 means use existing window and field table
         bit 5 if set, panel contains a field table
           (creates a new keyboard and puts it in field mode)
         bit 4 if set, panel contains input fields
         bit 3 if set, panel contains select fields but no input fields
   if the panel contains input or select fields, a keyboard handle is
     returned; either the window's current open keyboard or a
     newly-created keyboard object.  The caller should read that keyboard
     to obtain input from the panel.
