Ok, A6,A1 was a typo, I meant A4 - apologies. On the other hand, my

Dickens says that codes $31 to $FF are extended to a negative word

the fact that $31 does not seem to be allowed, Pennel and Dickens are
saying the same thing in different ways, Pennel is in fact correct.
According to Wikipedia, the story about Napoleon is legend with no basis

However, what is interesting is that road traffic statistics seem to
suggest that driving on the left is safer. The theory is that the
preponderance of right eye dominance results in statistically faster

Morning Marcel, Wolfgang,
Thanks for your replies.
Nope, that's where you differ with the documentation. First, the
variable area is (A6,A4), typo I guess, and second, the opcodes $FF31
to $ are for load/save, not $32 to $FF. Yes, the latter DO work,
but it seems that's more an

Ignore that. I'm a pillock. I've got my mental stack upside down again :o(

Morning Derek,
Many years ago I wrote many Hyperbolic function based on The Advanced
QL User Guide, by Dickens. All seemed to work fine.
Funny that. I was just wondering if anyone had ever done that sort of thing
when I was looking at Dickens last night. Spooky :o)

PS. I'm off to France next week, so any replies after today will be delayed

that should be fun. If you are anywhere around Marseilles,
Thanks.

Not with the LOAD/SAVE op code as far as I can see, they always take
6 bytes from the A1 stack and load back 6 bytes. There is no way
that I can see (using the maths package) to load and save a word for

Hi Marcel,
Yes, but nobody tells you that the data area is just for FP data.
True, but if I was setting up an area of storage I'd be sure (myself) to keep
my FP stuff well away from my other stuff purely because it's possible for the
FP stuff to wander all over my other stuiff if I get the
