That makes sense. It looks like you could store L1 as a variable like J and then use {J} later on.

not sure what you mean.

if you mean this...
"It looks like you could store L1 as a variable like J and then use {J} later on."
then No. L1 is a constant number, but you can use it's location {L1} as a variable.

"It looks like you could store L1 to a variable like J and then use {J} later on."
then i would say...

well you don't need to.  L1 is a constant. (34540 if i remember correctly), I would suggest you just keep using L1.
So you can do stuff like this for further locations: {L1 + J}

Well, happybobjr, you can store A*10+1+L1 or whatever into J and then do {J} and it will do the same thing as {A*10+1+L1}, just easier to type.

If you stored
{A*10+1+L1}
into J, would {J+1} be the same as {A*10+2+L1}?

Also, in
PtOn(x,y,Pic1)

If pic1 is an 8x8 sprite, what part of the sprite is located exactly at x,y?

Top left corner of that sprite block.

No.
What he means by that is you'd store A*10+1+L1 into J, not {A*10+1+L1}.

The advantage of compiling a program to run in a shell?
I'm not too sure myself, but...

1. You can give your Axe program an icon and a description that will appear when you look at it in a shell
2. DoorsCS programs can be slightly larger (by about 700 bytes, I think) then the normal maximum (although you can use Crabcake and circumvent the entire issue of memory altogether)

Is there any way to make this work? I need it for a game where the character can level up and then have different appearances.

Code: [Select]
If G=1
[hexadecimal]->Pic1
ElseIf G=2
[different hexadecimal]->Pic1
ElseIf G=3
[different hexadecimal]->Pic1
ElseIf G=4
[different hexadecimal]->Pic1
ElseIf G=5
[different hexadecimal]->Pic1
Else
[different hexadecimal]->Pic1
end

yes there is.

you need to do
[00000000000000000000000]->Pic1
then do

If g=#
[##################]->{Pic1}
elaseif g=#
[##################]->{Pic1}

.....
and so on

That doesn't quite work, as that is storing the pointer into Pic1, not storing the pointer as Pic1.  This will also modify your program if you use a shell like MirageOS.  Probably the best design would be something like this:

Code: [Select]
[SPRITE DATA 1]->Pic1
[SPRITE DATA 2]
[SPRITE DATA 3]
...

Pt-On(X,Y,G*8+Pic1
Where G=0 is the first sprite, G=1 is the second sprite, and so on

It increases the pointer by 8 bytes, since each sprite is only 8 bytes, it will move the pointer from the first sprite to the sprite after it.

What Builderboy's code is essentially doing is hardcoding in a list (technically a contiguous block of memory) containing data for a sprite.  Each sprite takes up exactly 8 bytes.
