So, Axe is pulling shenanigans.
Can someone tell me how to use the Pt-Command()->BUFF please?

Thanks.

You use it just like normal, but with the -> followed by the buffer on the end, where BUFF is any 768-byte buffer.
Pt-On(X,Y,Pic0)->L3 is the equivalent of Pt-On(X,Y,Pic0)r, for example.

Generally if you're trying to maximize speed, you keep the whole program in 15MHz mode EXCEPT DispGraph with grayscale modifiers and direct keys.  So you can simply do this to update the screen:

:Normal
:DispGraphr
:Full

I always have the auto opts file open when I'm coding, to try to keep my programs as small as possible. However, this just shows the size of things that are automatically optimized. Could you add a file that doesn't show optimization sizes, but just command/operation sizes in general?

I'm trying to convert a string to hex data, so if Str1 was "0123456789ABCDEF" then I would want to put [0123456789ABCDEF] into Pic1. Here's what I have so far, but it's not working right.
Code: [Select]
"0123456789ABCDEFG"->Str1
[00000000000000000]->Pic1
For(A,0,7
A*2+Str1->E
{E}-48->C
A*2+Pic1->G
C-((C>9)*7)->H
{E+1}-48->C
C-((C>9)*7)->M
H*16+M->{G}
I'm trying to convert the character values of the letters in Str1 into the numbers they represent.

I think A*2+Pic1 should be A+Pic1.

Does anyone know where the OS stores the current pen X and Y values?

Yeah, its E86D7 and E86D8.  I'll eventually have useful addresses tokenized so you won't have to look them up manually.

Tokenized addresses? What would you use for that?

Awesome job on the masked sprite routine!  I'm glad to see it finally implemented

Does anyone know how to change the allocated memory size for something without losing the contained data? For example, how does the operating system accommodate changes in program size while the user is editing a BASIC program?

EDIT - And another question: Is it possible to retain OS-style getKey functionality with custom interrupts enabled?

There are some complicated OS calls going on in that which involves a lot of data shifting and such.  I dont pretend to be an expert so you might want to hop onto IRC and ask calc84 or Iambian or any other Asm guru out there.

Yeah, there are several bcalls for that, but one of them is way too complicated for Axe, the other one i might be able to add that basically just allocates X number of bytes to an OS variable.  But every time you do that, you have to update your program pointer (and in fact all pointers n RAM if you're reading from many variables at once) since things move around during memory allocation.

The OS-getkey is definitely a possibility, but it slows down interrupts and produces non-uniform pauses.  I think I will use fnInt()r for that eventually so you can choose.

That would be a really useful routine for people who want to do some editing to programs :)
