Format of the Menu Mask

n A number displayed in the # column of a task can be entered here. The effect is the same as if the respective menu item had been marked with an X, i.e. the Connection is opened (if Status = OFF), and control will switch to this Connection.

C Return to the CFS program. The K1 key has the same effect of quitting the Menu system and returning to the command line of CFS. The menu mask can be reactivated at any time by entering a MENUE command.

A particular entry in the menu file will permit or prohibit the user from accessing the CFS "task", i.e. from using the "File Services".

E Terminate the Menu system and CFS. The ENDE function terminates all opened Connections with a DC (Disable Connection) command, and then terminates the CFS program.

If a Startup file containing a Shutdown command sequence was used to load CFS (see Chapter 20), then entering 'E' will cause the Shutdown command sequence defined in the Startup file to be executed. In this case, the open Connections will not be terminated by the Menu system with a DC command.

M Modify. The Modify menu will be invoked. The Modify menu has space for up to 20 entries, and allows the individual menu items to be modified, copied, deleted, or their sequence to be changed. Changing the sequence of the menu items can shift menu items from the background to the main mask, in which only Connections numbered 0 through 9 are displayed.

S Save. 'S' will overwrite the menu file with the current values in operation. Normally, the user will only be asked if the menu file should be updated after exiting the system with 'C' (CFS) or 'E' (ENDE).

If the user does not have permission to invoke CFS (no 'CFS' entry in the menu file), the 'M', 'C', and 'S' entries in the global input field will be ignored.
