In our old character-based versions there were other numbers that made sense, but the only numbers that make sense to use anymore are 0 and 3.
MODE STOP 0 is the default. In this case both the Data and the Windows Menus support a choice in them labeled DCL. With this choice the user can
get to DCL from these Menus.
MODE STOP 3 removes the DCL choice from the Windows and Data Menus. Your users will not be able to get to DCL unless you provide that access through your own utility procedure. There would be your oportunity to ask for a password, or somehow restrict who can get to DCL when your applica- tion is running.
MODE STOP is reset to default status (0) each time you do an OPEN
, so you must reestablish it after any OPEN.
