Logical Names

Specifying a translation mode:

$ ASSIGN/USER

$ DEFINE/USER
• Logical names are DEASSIGNed at next image run-down
• Does not require privilege

$ DEFINE/SUPERVISOR
$ ASSIGN/SUPERVISOR
• /SUPERVISOR is the default
• Does not require privilege

$ ASSIGN/EXECUTIVE
$ DEFINE/EXECUTIVE
• Requires CMEXEC privilege

There is no /KERNEL qualifier. Kernel mode logical names must be created by privileged programs (requires CMKRNL privilege).

Access modes of logical names specify additional levels of privilege or supercession.

More privileged access modes (called “inner” modes) require privileges in order to replace the current definition of a logical name. However, another translation of a logical name can be created in a less privileged (“outer”) mode. Such a condition creates an “alias” of the more privileged logical name.
