VM/CMS CP DISABLE Command
The DISABLE command prevents access to VM370 by 270x and local 3270's
Priviledge Class A or B
Issuing the DISABLE command will block 270x terminals and locally attached 3270's from accessing
VM370. For existing sessions the block will not take place until the user has logged off or
disconnected. Remote 3270's must be disabled thru the use of the NETWORK command.
