These messages provide XAcc initialization and organization. This is 
the only part of XAcc which has to be implemented in a different way 
for single- and multi-tasking GEM versions. Note that the procedure 
described for 'multitasking' actually only depends on the existence of 
appl_search and hence on an AES version number >= 4.0. If some future 
single-tasking AES supports appl_search, the "multitasking" 
initialization should be used. Multitasking AES versions with a 
version number < 4.0 should never exist; to be on the safe side, 
applications should not attempt to use XAcc if such a situation is 
detected.
