Oh, you mean a 3-character static pointer. Yeah, you can use them. And the name of a static pointer contributes nothing to the compiled program size. The only quirk about static pointers is that, when adding a pointer to string data in the form of:
Code: [Select]
:"String here"→Str___A zero byte is added to the end of the data automatically.

Code: (Axe) [Select]
:"This"→Str000
:"is"→Str001
:"a"→Str002
:"test."→Str003
:Data(Str000r,Str001r,Str002r,Str003r)→Str0        . The pointers to each string
:Disp {A*2+Str0}r        . Where A is the index of the string
So, it would work with that Data( line?

Yes, that would work. The one thing you have to watch out for when using that method though is the 150 pointer/label limit, which you could hit pretty fast that way. Unfortunately, there isn't really a way around this except for giving the first string a pointer, not giving pointers to every other string, and manually calculating the pointers for all the other strings based on the pointer to the first string. Like:

Code: (Axe) [Select]
:"This"→Str00
:"is"[00]
:"a"[00]
:"test."[00]
:Data(Str00+0ʳ,Str00+5ʳ,Str00+8ʳ,Str00+10ʳ)→Str0
:Disp {A*2+Str0}ʳ

That could be pretty tedious, and getting anything wrong or changing one string would require you to adjust the data for every other string after it. You'll have to wait for Axe v2 to get around the 150 pointer limit. :P

Thanks anyway

Oh crap!!!
And to think i was going to have each of the 151 Pokemon's name in a string...
* Happybobjr hugs runner.
How can I easily add a 0 byte to a string or what ever, 151 times?

Happybobjr, I think your best bet for storing the names of Pokemon would be to make each name a constant size. As far as I can see, the names of Pokemon in the Generation I games were limited to 10 characters, so you could make each name be 10 bytes long. To display the names, you would have to copy the 10 bytes to another location in RAM where you can add an 11th byte, a zero in case the name was 10 characters long and didn't have a terminating zero already.

Thank you.  Wish I didn't have to waste all those bytes though...

Actually, there's another way. Watch:

Thanks to Axe auto-opting static pointers,

Code: (Axe) [Select]
:"Bulbasaur"→Str000
:"Vsaur"
:[00]
:"Chucknorrissaur"
:[00]
:Data(Str000ʳ,Str000+10ʳ,Str000+16ʳ)

is exactly the same (in terms of size, time, code, etc.) as

Code: (Axe) [Select]
:"Bulbasaur"→Str000
:"Vsaur"→Str001
:"Chucknorrissaur"→Str002
:Data(Str000ⁿ,Str001,Str002)

except that it doesn't use up two more of those 151 pointers you're allowed to have. That solve your problem? :)

Not sure why I decided to use offsets instead of static pointers in my example. Changed that. But yeah, that's pretty much what I suggested to Darl181 earlier. Although where are these offsets coming from? The +19 and the +6?


EDIT: Side note, why do you use the ⁿ symbol in your code Deep Thought? Why not use the ʳ that I use? :P

That's supposed to be a 10 and a 16 :P Not typing well today.

Because I couldn't find that character anymore for some reason. How'd you find it?

Thank you! That is awesome!

And speaking of turtles, ALT+26 gives you the store arrow → :) It's really useful.

That's one of the tokens, iirc
I'm guessing he meant ► like ►Dec

So, while I was trying to do Alt+26 (Which doesn't work for me, btw), I accidentally did Alt+2602 and got ☂.  I then tried Alt+2603 and got ☃. :D

EDIT: Wow, way to get uber-ninja'd.  I even did my own ninja, me-thinks!
