LINE(nnnnn) - NJE/RJE BSC Lines

z/OS JES2 Initialization and Tuning Reference
SA32-0992-00

The LINE(nnnnn) statement specifies the characteristics of one teleprocessing line to be used during remote or network job entry (for BSC NJE and RJE terminals). Define each teleprocessing line by a LINE(nnnnn) statement with a unique value (1-65535).

Use the subscript on this statement name to specify individual lines (nnnnn), a range of lines in either ascending (n-m) or descending (m-n) order, or a generic range in ascending (n-*), descending (*-n) order, or an asterisk (*) to indicate all lines. The valid subscript range for the LINE statement is now 1–65535.

There are four parameters that you use to define the number of transmitters and receivers for a line. They are: JRNUM=, JTNUM=, SRNUM=, and STNUM=, and are collectively referred to as xxNUM= parameters. If all the xxNUM= parameters are specified as DEFAULT, no devices are dedicated to this line unless a device is specified on either an L(nnnnn).ST(n) statement or an L(nnnnn).JT(n) statement for this line. In that case, a full set of transmitter and receiver devices is dedicated as specified on the NJEDEF xxNUM= parameters. If any of the xxNUM= parameters are set to a value other than DEFAULT, a full set of transmitters and receivers is dedicated to the line, with default values taken from NJEDEF.
  • If a set of transmitters and receivers are dedicated to the line, the line may not be used for RJE.
  • If transmitters/receivers are not dedicated to the line, it may still be used for NJE.
  • A default set of transmitters and receivers is assigned when the NJE link is started, and detached when the NJE link is ended.
