Interesting... this seems to be the opposite of what the M680x0 programmer's manual states: "If the effective address is specified by the predecrement mode ... ... For the MC68020, MC68030, MC68040, and CPU32, if the addressing register is also moved to memory, the value written is the initial register value decremented by the size of the operation. The MC68000 and MC68010 write the initial register value (not decremented)." Daniele _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
