NAME : HCPEXQBK DESCRIPTION: exec() request block user data mapping DSECT : EXQBK FUNCTION : This DSECT maps the user data in a REQBK for exec() processing. LOCATED BY : REQUDATA in the REQBK. CREATED BY : N/A - mapping block only. DELETED BY : N/A - mapping block only. SERIALIZED : N/A - serialization is on the REQBK whose REQUDATA section this block maps. RELOCATION CONSIDERATIONS : None COMMENTS : This control block is a mapping for the REQUDATA section of the REQBK used for exec() processing. No storage is acquired for this block. It is important, however, that changes in the size of the REQUDATA section of the REQBK be reflected here.
