Stanley quotes from pages 1-8 and 1-9 of the M68000 Programmer's Reference Manual: "... For this reason, the MOVE from SR instruction has been added to allow user program [sic] unhindered access to the condition codes." If Stanley really understands the "*subtle* implications" of the questions being raised, then he obviosly realizes that this is a typo and should read "... the MOVE from CCR instruction has been added..." this allows a user program to get at the Condition Code Register portion of the Status Register.

So the MOVE SR is a bug in the documentation as well as a bug in the design. And in the *fifth* edition too. Boy, Motorola just can't do anything right. :-) Hmm, I got a ton of flames for pointing out one bug, I hope you don't get quite as much for pointing out the other. I happen to have this well-tested asbestos suit for sale - guaranteed flame resistant. Call me and we can talk :-) Stanley Chow BitNet: schow@BNR.CA BNR UUCP: ..!psuvax1!BNR.CA.bitnet!schow (613) 763-2831 ..!utgpu!bnr-vpa!bnr-rsc!schow%bcarh185 Me? Represent other people?

Is there a way that we can keep dorks like Stanley Chow, who obviously have nothing creative to add to the Amiga discussion, out of comp.sys.amiga? I'm getting sick of having to read all this garbage at 1200 baud! Bashing motorola, bashing the amiga, the fm towns, etc... My k key is getting worn out! Gimme a break! -Vic Ricker vmr@hcx.psu.edu
