2 GBL
 Appending a /GBL keyword to an assign command causes the assignment
 to apply to all terminals, displays all global assignments, or removes
 a global assignment.
2 LOGIN
 Appending a /LOGIN keyword to an assign command causes the specified
 assignment to become effective for the issuing terminal when that
 terminal logs in, displays login assignments for the issuing terminal,
 or deletes a login assignment.

 The assignments for that terminal can be created, displayed, or
 deleted.
2 TERM

 command to apply to the local assignments for the terminal ttnn:.  The
