NAME       : HCPEXDBK
 DESCRIPTION: exec() data block
 DSECT      : EXDBK
 FUNCTION   : This DSECT maps the data necessary to perform
              the communication across the asynchronous
              portion of exec() processing.
 LOCATED BY : registers in the exec() modules
              REQDATAP - data pointer in the REQBK
 CREATED BY : HCPEXD
 DELETED BY : HCPEXC, HCPEXD
 SERIALIZED : Indirectly, by the request chain lock.
              The contents of the EXDBK are only valid
              and usable if the request block pointing
              to it has been properly dequeued.
 RELOCATION CONSIDERATIONS : None
 COMMENTS   : None
