LINE(nnnnn) - NJE/RJE BSC Lines

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.
