Runer already made an Axiom for that. But I would still like to see your version. Who knows, yours may be better.

Quick question - let's say that I'm using L1 to hold a lot of data, but occasionally I would want to store lots of more data - more then L1 can hold.
Is there a way to 'chain' memory spaces, so that if I were to overflow L1, I would write my data to an appvar or other buffer instead?
Effectively, it would treat L1 and an appvar as one huge block of memory.

yeah, to do that you would have already created an appvar witha  pointer to it, and know the size of the buffer you're using (I'll use appbackupscreen for now because I most definately know that offset) At L3 and a pointer to your appvar at P:

EDIT: and btw this is just to read code one byte at a time, with X as your offset:

Code: [Select]
{L3+X+((L3+X>L3+767)*(P-L3+767))} -> Y
Disp Y >Dec

Quigibo, can you have the parser check Axioms first and then check the actual Axe code?  This would allow redefinition of various Axe functions and allow different behavior.  For instance, if you were writing some BrainFck in Axe and had an Axiom for it, you could use + in the way BrainFck requires it to be used in. :)

I am pleased to announce that I have finished the Axioms finally.  I will be distributing pre-release versions to a few people later today after I do more testing with them.  They are extremely powerful right now.  New features include: recursive axiom chain calling, distinct commands using identical tokens but based on different arguments, r modifiers, store arrows, and shells; native axe routine calling, relative and absolute referencing for any 2-byte immediate instruction, including calls, jumps, and loads; easily add data tables to aid your axioms, new tokens specifically for axioms, and a lot of other features I'm probably forgetting.

Basically, you have nearly complete control with the new commands.  I'm looking forward to some really great libraries ;D  I'm also going to make a mode7 example program using the new library since I haven't done any example programs for a while.

I don't want to look through the axioms first or else the parsing will be slower since it will have to scan every single axiom before it starts looking at the regular commands.  Also, I don't have axiom support for operators since they require a lot of special form stuff like auto-optimizations and operation on parenthesis.

That's great Quigibo! I can't wait to see the Mode 7 engine too. I wonder if Runer112 will release his raycaster Axiom soon afterward too. :P

Is there a way to store a TIOS picvar, say, Pic1, to a buffer without using dispgraph?

Yes, you can use the Copy() command to take the data from the OS var and place it wherever you like. :)

Yep, remember that the buffer is just L6 and that the back-buffer is just L6. So Copy(POINTER,L6,768) should work :)

Would the picvar be required for the executable to run, or just to compile?

Another thing.  You know how {E8447}+24 is the contrast level?  What points to the Ans variable?

If you're accessing it during runtime, it's required to run.

Ans is just like any other variable: it could be anywhere in user mem. You have to find it with GetCalc() (or store to it/recall it with Axe's built-in routine).

So, that would be like Getcalc(Ans)?  The goal is to store a token, either two-byte or one-byte, into ans.
