This mode is called once during program initialisation. As explained above RAA will request optional titles management of the titles bank RAAS n. For example, subprocessor 3 accesses its bank via:-
integer ldraas
equivalence ( laraas(7,3), ldraas)
If a subprocessor needs other title banks then it must request them
itself. During this step subprocessors should set up bank address mnemonics
using the routine RAA_SUMM_WORD_ADDR as described in section
8.2.2.
Return codes from subprocessors are ignored.
