To print it out, I assume. I really need to read this

586. You carry with you a copy of the z80 instruction set, printed on one piece of paper, in your calculator case (I have done this before. It required printing 16 pages to a sheet, but it fits on one side!  )

O_o That. Is. Awesome. Can't wait to see more progress!

Actually, something I missed: if the counter will hit 0 n times per second, then taking over an nth of a second will cause it to skip a cycle. (Very similar to interrupt routines, in fact) But, again, unless you do a lot of stuff, this shouldn't be a problem

Also, couldn't it be {A} to be more consistent?
That implies a memory read from the pointer stored in A, which is not consistent. The official z80 syntax makes this mistake too, naming an instruction jp (hl) instead of jp hl
Ah, right, my bad. My questions about {L1} and {{L1}} become about (L1) and ({L1}), then Quigibo, that seems about the best way to do it short of SMC. Edit: Ninja'd with respect to Quigibo's question.

No, it should as accurate as the interrupts are as timers, providing that you don't miss when the timer is 0.

Just a suggestion, but would it be possible to document which commands have an effect on interrupts?
(I ask mainly because I just learned that Disp >Dec disables them)

It will be a set of extra parenthesis:
Goto A Jumps to label A
Goto (A) Jumps to the address that the Variable A holds
My main question was "If I have a label A, how do I get its address?" Also, couldn't it be {A} to be more consistent? (Also, will, say, (using brackets, not parentheses) {L1} jump to the beginning of the L1 saferam area, and will {{L1}} jump to the address at {L1}?)

What it does is perform an action at a certain rate. Lemme explain it for you (Note that it is only an example ) .Initialize variables for the program
0->C->X
.Just to make it look nice
ClrHome
.Set up the timer interrupt
fnInt(T,0
.Main program loop
Repeat getKey(0)
.If the counter is zero
!If C
.Display and increment X and put a new line
Disp X+1->X>Dec,i
.Reset the counter to 50 again
50->C
End
.Because Disp is silly
FnOn
End
.Clean up and return
LnReg
Return
.The timer
Lbl T
.Just decrement C
C-1->CIn short, it's an example program that counts up at regular intervals. Note that the only weakness to this method is, if you don't reset the counter when it reaches 0, it will have to count down all the way from 65535 to 0 again. (This normally should not be a problem)

Sounds cool! What'll the syntax for getting the value of a function pointer be? Can't wait, keep up the good work!

Garbage collect might fix it. And it's not that two programs/appvars/etc. can't be put into one sector (that'd be awful ), it's that those and apps cannot be in the same sector. This means that you could have 63KB of Archive free, but be unable to send even a one-page app because 1KB of that sector contains a program/appvar/etc.

The code I just posted is fine and tested to work.
The problems that I solved were 1) I had forgotten LnReg (that's why it crashed before) and 2) For some mysterious reason, Disp, Disp >Dec, and possibly other OS routines disable interrupts, which means I had to insert an FnOn into the loop (it also could have been put in the If instead of the Repeat)
Number 2 is the one I'm going to bother Quigibo with.

0->C->X
ClrHome
fnInt(T,0
Repeat getKey(0)
!If C
Disp X+1->X>Dec,i
50->C
End
FnOn
End
LnReg
Return
Lbl T
C-1->CNever mind, I figured out why my code wasn't working... (and something I can bug quigibo about...)
Edit: Indented for readability.

xdelta patch os.89u patch.xdelta patchedos.89uwhere os.89u is the original OS file, patch.xdelta is the delta file, and patchedos.89u is what you want the patched OS to be named.
Edit: This is what I understand by reading the docs posted a couple up. Lionel will have to make sure I'm correct.

I'm not sure how feasible that would be, though it could be helpful. In the meantime, http://ourl.ca/7043 is a topic where someone was trying to do a similar thing  I just bumped it, so eventually there should be a response.
