WEIBK Prolog

 NAME       : HCPWEIBK
 DESCRIPTION: Work Element Identifier Block
 DSECT      : WEIBK
 FUNCTION   : Identifies a single WEBBK, functioning basically
              as a header for that WEBBK
 LOCATED BY : SNAINN    Field of SNABK - start of input chain
              SNAOUT    Field of SNABK - start of output chain
              SNAINNL   Field of SNABK - last in input chain
              SNAOUTL   Field of SNABK - last in output chain
              WEINEXT   Forward chain
              WEIBACK   Backward chain
 CREATED BY : HCPVCVCI - Build and chain a WEIBK to input chain
              HCPVCVCO - Build and chain a WEIBK to output chain
 DELETED BY : HCPVCVIN - Clean-up SNABK input chain
              HCPVCVUT - Clean-up SNABK output chain
 SERIALIZED : SNALOCK   Shared-exclusive lock that serializes
              the fields SNAINN and SNAOUT, which
              anchor the chains of WEIBKs and WEBBKs
 RELOCATION CONSIDERATIONS : None
