File: _ttyradi.p

Description:
    Draws a tty style radio-set in an editor widget (in order to simulate what
    a TTY terminal would be doing).
    
    For example:         Using:
       ( ) Item 1          _F._LIST-ITEMS (contains the buttons)
       ( ) Item 2
       ( ) Item 3

Input Parameters:
   h_ed        : the handle of the editor widget (I do check to make sure the
   	         h_ed:TYPE is EDITOR.
   is_horz     : FALSE if radio-set is VERTICAL
   radio-btns  : the char radio-button phrase.
   
Output Parameters:
   <None>
