Primary Environment Modes

When the primary menu is displayed, the primary environment is operating in base NCL mode. There are two other modes of primary environment:

• OCS
• MAI-FS

These modes are invoked when the primary menu procedure issues a SETMODE command to modify the primary environment. When these alternate modes are terminated, the primary environment returns to base NCL mode.

For example, if a user is authorized to access OCS and enters the O option on the primary menu, OCS is invoked using the SETMODE OCS command. This alters the primary environment so that it operates in OCS mode. When users exit OCS, they are returned to the primary menu, and the primary environment operates in base NCL mode.
