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.
