Accumulator A - C flag - stewartraymond - Mar 31 19:56:28 2009
Accumulator A contains $FF, and the C flag is cleared. If a INCA instruction is executed,
the C flag will be ____________________.
1. set
2. cleared
3. cannot be determined
4. added to Accumulator A, so that it contains $01

Cannot provide the answer just now because the manual is out of reach but it
is maybe a little funny, I thought this question would follow the original
DECA question maybe due to typo DECA/INCA?
Guess the answer would be unaffected but this must be double checked.

Sorry for not reading properly, *C* flag this time, not Z flag...

RE: Accumulator A - C flag - Rob Mora - Mar 31 22:05:41 2009
I wouldn't worry about it too much, the question doesn't even really deserve
an answer. I'm all for helping students when asking valid questions when
they're working on projects or whatever (wasn't *that* long ago I was one),
but I don't think this list is for doing their homework assignments for
them. And really, it's such a basic question that if they can't find the
answer to this on their own... well then, I wish them good luck passing
their class, because they certainly need it.
I hesitate to even respond and add anything to it, but this is the second
one of these from the same guy.

Re: Accumulator A - C flag - stewartraymond - Mar 31 22:37:17 2009
Thanks for the encouragement, and I will take heed of your suggestion and withdraw from
this group to help with certain questions I seem to have a hard time understanding. As of
today, I have been taking an extra course through my employment's computer operation
system for almost an year now, but starting to get a little discouraged when I struggle
with certain aspects of this curriculum, even though I have worked in computer operation
for over 10 years.
I think I should seek a tutorial program to complete this course as soon as possible.

RE: Re: Accumulator A - C flag - Anders Friberg - Mar 31 23:41:14 2009
Don't be discouraged, best way to learn is by reading/comparing/doing
yourself, not asking. Regarding courses I think that you can expect them to
contribute max 10% to your education, the rest 90% must come from your own
interest, curiosity, experimenting etc.
In the academic world it is probably common to attend different classes just
to get points (and never ever use that knowledge again), that is a special
case but you said you were employed.

It's available on-line, detailed enough to easily find the answer.
