EXQBK Prolog
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.
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.
