 NAME       : HCPNDCBK
 DESCRIPTION: Virtual Network Interface Card block
 DSECT      : NDCBK
 FUNCTION   :
              Define a structure to represent a work area used
              for processing a DEFINE NIC, DETACH NIC or SET NIC
              command.
              A new NDCBK is allocated for each command.
 LOCATED BY -
   Local pointer for the duration of command processing
 CREATED BY :
              CP DEFINE NIC command processing (module HCPNIC)
              CP DETACH NIC command processing (module HCPNIC)
              CP SET    NIC command processing (module HCPNIC)
 DELETED BY :
              CP DEFINE NIC command processing (module HCPNIC)
              CP DETACH NIC command processing (module HCPNIC)
              CP SET    NIC command processing (module HCPNIC)
