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
