On VBUILD
name is optional. If a syntax or definition error is detected with this statement during activation of the major node, name appears in the message issued to identify the error.
The optional name you give to this definition statement can be the same as the name VTAM® gives to a major node and its definitions when they are filed in the VTAM definition library. The name VTAM gives to the major node is used when messages are issued regarding the node's status.
