REQBLOCK REQBLOCK defines data and information for a request for file processing by the DMTMFT line driver.
The first four fields of this DSECT form a GIVE request table, which is described in "GIVEE: A GIVE Element", in this section.
The next seven fields of this DSECT for a GIVE request tuffer in the format of a File
Request Element, which is described in "Appendix C: RSCS Request Elements."
