ASSIGN options for partitions

In addition to the INPARTN option , there are three other ASSIGN options to help you in programming for a partitioned terminal.

The PARTNS option tells you whether the terminal associated with your task supports partitions, and the PARTNSET option returns the name of the current partition set (blanks if none has been established). The fourth ASSIGN option, PARTNPAGE applies only to logical messages, which we talk about in Partitions and logical messages.
