Description
  VReadMenucomFile reads the vertical and horizontal menu information, the
current command, process and function names from the MENU.COM file. The
value of the process is the name of the process if the associated command
calls a process, else it's an empty string. The value of the function is
"vertical" if the menu in the next level is to be displayed vertically, 
"horizontal" if the menu in the next level is to be displayed horizontally,
or an empty string if no menu is to be displayed. VReadMenucomFile should be 
called after VSelectMenuItem to get the name of the process or function 
associated with the current command.
