In binary,

%00000001 = 1
%00000010 = 2
apply xor to each bit
%00000011 = 3

it's not the difference between 16 or 8 bit this time, but between all bits at once, or bit  by bit.
so not 1 xor 2, this will result 0
but 1 xor 0 results 1 at the least significant bit
and 0 xor 1 also results 1 at the second least significant bit
this results a 3

nemo, I believe both in Axe are bitwise. The plot-style ones are just 16-bit whereas the normal ones are 8-bit.
I'm pretty sure (but not 100%) that nemo's right.  Quigibo? :)

Edit:  He was wrong, and so was I...  almost 100% != correct... ;D

i'm wrong. i tested it on-calc in axe, it must be bitwise since where A=6 and B=5, A-5 xor (B-3) results in true.

Hmmm im having weird problems with interrupts.  Sometimes i've had them randomly turn themselves off.  Here is the exact code:

Code: [Select]
.AXE
ClrDraw
DiagnosticOff
FnOn
fnInt(IN,0)

9->C

Repeat getKey(15)
Pxl-On(C/2/2/2/2,0
DispGraph
End

LnReg
Return

Lbl IN
C+1->C
I use the pixel moving thing because displaying text messes with interrupts i also noticed.  Every one in a while when you run the program the pixels will stop advancing.  I have run some tests, and there is no crash, the rest of the program continues to run, but the interrupts have turned off.

Hmmm... I'm almost certain that the problem is with the DispGraph routine becasue it doesn't happen with just displaying C as a number.  Try adding an fnOn after each dispgraph.

Calc84maniac, are you sure the

ld a,i
push af
di

pop af
ret po
ei
ret

Will preserve interrupts even when these commands themselves are interrupted?

The commands won't get interrupted, because you are doing di at the start of the code.  I don't know what ret po is, but I bet that would be your problem, which would cause it to not get to the ei line.

Quigibo: I'm pretty sure that it would still preserve interrupt status, even when interrupted, because a properly done interrupt (such as the TI-OS one, and the one built into Axe) might as well not have executed as far as the other code is concerned (as long as you're not using the shadow regs, of course).
graphmastur: When you do "ld a,i" or "ld a,r" the current interrupt status (enabled, disabled) is stored in the parity flag. Set (pe) means interrupts are enabled, reset (po) means they were disabled.
So, if interrupts were disabled before, the "ret po" line will cause a return, skipping the re-enabling of interrupts.

Most interrupts are currently not compatible with applications at the moment.  Any system call will not switch the correct page back to the application and cause crazy stuff to happen.  There is a fix I can do by making sure I swap the page before the interrupt quits which is what I'm going to have to do for applications.  So for now, DO NOT use interrupts with applications.

I'm not entirely sure if this is a bug report or a feature request, but attempting to use a negative number in a Data() array returns a bad number error. (This occurs even if you use an r modifier)

I think when storing data this way, it needs to be unsigned, meaning without r it's 0 through 255, not -128 through 127, and with r, it's 0 through 65535, not -32768 through 32767.

I don't think that would be the problem. Bcalls always swap the previous page back in after completion. The real problem is when executing a bcall outside of an interrupt and the interrupt fires while the page is swapped. The solution to this would be to swap the page upon interrupt and restore it upon completion.

This isn't a problem with the parser, just the Auto Opts file. Try to spot the (once seen, very gross) error:

Code: [Select]
SHORT means less than 256 bytes
CONST means any size
=/= is a "not equal sign"
>=  is a "greater than or equal sign"
<=  is a "less than or equal sign"

Do you mean SHORT being less than 256 bytes? Bytes shouldn't be there since short is one byte and it's the bit value that can range within 256 values
