View Ref-File13.13.2.2.1  Basic XAcc messages                                   TOS

ACC_ID    = 0x400
ACC_OPEN  = 0x401
ACC_CLOSE = 0x402
ACC_ACC   = 0x403
ACC_EXIT  = 0x404

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.
