Specifies the initial operating condition of the line for lines that can operate alternately in network control mode and emulation mode.
USE also allows you to specify SDLC lines in the NCP generation for line slots that do not have physical lines attached, but which can be attached later, and allows you to redefine a line that is attached.
See NCP, SSP, and EP Resource Definition Reference for
proper coding of the USE operand.
- USE=EP
- Indicates that the line operates initially in emulation mode. Prevents the line from being activated unless a VARY ACT command is issued for it. Activating such a line with a VARY command gives the line to VTAM and NCP, whether or not it is in use by EP.
- USE=NCP
- Specifies that the line operates initially in network control mode.
- USE=REDEF
- Specifies that the line is being used, but can be changed to a spare line. The mode of operation is assumed to be NCP. USE=REDEF is used with the MODIFY command to change it from a defined line to a spare line and vice versa. Note that a line defined with USE=REDEF must be the only line in a line group.
- USE=SPARE
- Specifies that the line is being defined for later use, although
there is no line attached to that line slot in the NCP.
The mode of operation is assumed to be NCP. Note that a line defined with USE=SPARE must be the only line in a line group.
