NAME       : HCPWIDBK
 DESCRIPTION: Work Indirect Data address BlocK
 DSECT      : WIDBK
 FUNCTION   :
              This block is used to contain a list of indirect
              address words (IDAW) and counts that identifies
              discontinuous storage buffers to IUCV
 LOCATED BY :
              WEIWIDBK - Address of buffer list WIDBK
              (located in WEIBK)
              WEIWIDSN - Send list WIDBK copy address
              (located in WEIBK)
              WEIWIDAN - Answer list WIDBK copy address
              (located in WEIBK)
 CREATED BY :
              HCPBOYGO - Logo WEIBK builder
              HCPVCERI - SNA Full-Screen Read Interface Routine
              HCPVCMIX - IUCV SEND issuer
              HCPVCYSM - SNA Full-Screen and DIAL Simulator
 DELETED BY :
              HCPVCERI - SNA Full-Screen Read Interface Routine
              HCPVCFRD - SNA Full-Screen Read Initiator
              HCPVCGWT - SNA Full-Screen Write Initiator
              HCPVCMIN - SNABK input chain control block releaser
              HCPVCMIX - IUCV SEND issuer
              HCPVCMUT - SNABK output chain control block releaser
              HCPVCXCU - Unchain an eligible VSM logo WEIBK
              HCPVCYSM - SNA Full-Screen and DIAL Simulator
 SERIALIZED :
              None
              Since this block is only accessed thru a WEIBK, access
              to this block's data must be serialized thru the
              owning WEIBK's serialization.
