By the way, using and not(mask) is actually much less optimized than doing and inverted_mask. If you're using a binary mask, change all the 0's to 1's or vice versa. If you're using a decimal mask, just subtract the mask from 255.

Ok, I have a very newbish question. Are there the binary and,nand,or,xor,etc ops in Axe ? Not that (4 and 2 = 1) because 4 and 2 aren't 0 but that (00000100 and 00000010 = 00000000) ?

In Axe, the logical operators are binary operators. 4 and 2 equals 0 in Axe.

It's and. 4 and 2 should actually return 0.

I think the reason bitwise expressions work in if statements is because it's only manipulating one bit.  They're essentially doing the same thing, iirc.

EDIT:
* Darl181 pokes again for some tutorial or another on bitwise expressions to be put in the docs ;)

Yeah, that's why If 5 and 6 returns true, since

    %00000101
AND %00000110
=== %00000100

but If 4 and 2 returns false, since

    %00000100
AND %00000010
=== %00000000

Ok...
I went to compile DS in 1.0.1 and got a "Bad Flash" error pretty much instantly.
What exactly causes this to happen?

EDIT: nvm, just a really fun axe bug x.x

Hi, I'm trying to create a new string randomly with letters from another string. This is what I have so far and it keeps giving me Bad Symbol error. I'm using Axe 0.5.3.

Code: [Select]
.RANDTXT
"0123456789-+/*^,()"→Str0
{Str0}+rand^18→Str1
Disp Str1

I am no Axe expert, but I don't think you can store a var to a pointer. (I am probably wrong)

or would it be better if I try to do this
Code: [Select]
{Str0+rand^18}→Str1?
Make a string with the byte at rand^18 of the string Str0 is pointing to and reference it with Str1?

Try the latter.  As you're probably aware the brackets denote pointers.  What the initial code does is get the pointer to Str0, return the value of the byte there, then to that value add rand^18 to it.  I'm guessing that's what you're not trying to do :P
Also, iirc, you'll need to define Str1 before hand. 
Another thing, strings are zero-terminated.  That means the string lasts until it hits a zero.  So if you don't explicitly put a zero at the end of a string (unless you're defining with quotes (or maybe it always does that, I haven't tested it) ) the string could stretch for almost any amount.  Not good.

Assuming you're storing only one byte: [0000]→Str1 should work.  Then put the second code you posted. Read the post after this.

Please note that because Axe uses left to right order of operations that code isn't doing what you want.  It's doing {(Str0+rand)^18}->Str1 though you probably want {rand^18+Str0}->Str1 .  In addition, I'm pretty sure you want {Str1} instead of just Str1 .  Good luck with your program! :)

I've tried what you said and it compiled nicely. I ran the program, it ran but the program return anything, it just says Done.

I want a 16-letter string so that's 32 0's for defining the string

Code: [Select]
.RANDTXT
[00000000000000000000000000000000]→Str1
"0123456789-+/*^,()"→Str0
For(I,1,16
{rand^18+Str0}→{Str1+2I-2}
End
Disp Str1

Why doesn't it display the string?

Just as a hint/rule of thumb, you can count from zero--so that would be For(I,0,15).  Also iirc parenthesis, for the most part, should be closed.

At what part does it crash?  What might help figure out what's going on (because frankly I'm kind of confused at this point as well, I'll prolly have to test it or something :P): put in some Disps so you can tell how far it gets into the code before it goes.

Is this the entirety of the code, or is there something else in the program that might be messing with it?
