Network control program major node

To define a network control program (NCP) major node, code the VTAM® and NCP definition statements detailed in this section, and file them in the appropriate VTAM definition library. The name under which the major node is filed must match the NCP load module name on the NEWNAME operand of the BUILD definition statement.

Information required by VTAM to communicate with the NCP and its attached devices is provided to VTAM by coding VTAM definition statements and NCP definition statements with VTAM operands. The VTAM definition statements and operands must be coded in the NCP major node, even though they provide no information to the NCP.

Definition statements in the NCP major node can be divided into the following categories:

VTAM only: Statement is processed by VTAM only.
VTAM and NCP: Statement contains operands that are processed by both VTAM and by the NCP generation process.
If there are any VTAM-only operands or restrictions on the statement, you will find a description in this document, but the description of the whole definition statement is in the NCP, SSP, and EP Resource Definition Reference.
VTAM and NCP, no VTAM requirements: Statement contains operands that are processed by both VTAM and by the NCP generation process, but it has no special VTAM requirements and should be coded as described in the NCP, SSP, and EP Resource Definition Reference.
NCP only, with VTAM requirements: Statement contains operands processed only by NCP, however there are special VTAM requirements.
See NCP, SSP, and EP Resource Definition Reference for a description and VTAM requirements.

The following list shows the definition statements used by VTAM in node.

PCCU: VTAM only
BUILD: VTAM and NCP
HOST: VTAM only (requires NCP V4R3 or later)
SYSCNTRL: VTAM and NCP
LUDRPOOL: NCP only, with VTAM requirements
PUDRPOOL: NCP only, with VTAM requirements
PATH: VTAM and NCP
GROUP: VTAM and NCP
LINE: VTAM and NCP
CLUSTER: VTAM and NCP
TERMINAL: VTAM and NCP
GROUP: VTAM and NCP
LINE: VTAM and NCP
PU: VTAM and NCP
LU: VTAM and NCP
NETWORK: VTAM and NCP
FRSESET: VTAM and NCP
GWNAU: NCP only, with VTAM requirements
GENEND: VTAM and NCP, no VTAM requirements
