This is axe, not BASIC. L1 in axe is just another pointer to a location in free RAM. You can use appvars to store savefile data in. There are some great tutorials here about appvars.

Well, if you want to save stuff temporarily wile in the program, you can use safe RAM areas like L1.
There are 712 bytes, and you can refer to them like: {L1}, {L1+1}, up to {L1+711}.
Of course, you can also store stuff into them.

As far as saving goes, like saving a high-score, etc. You can use appvars. To do this, you do:
GetCalc("appvTEST",2)->A     //make an appvar called TEST which is 2 bytes large and store it into pointer A
B->{A}r              //When B is your highscore, store it into A (the appvar) with 2 bytes. (using the superscript r)
I'd also refer to this tutorial about external vars.

Also, welcome here. Please introduce yourself in this thread: http://www.omnimaga.org/index.php?board=10.0


EDIT:

Well... You could at least have a look at those tutorials first

I really need a sort of list so i can store coordinates in it can someone help me with that ?

Exactly. Rather than doing "L1(1)", do "{L1}". same with "L1(3)", do "{L1+2}".


EDIT: again

Ok thank you it works
but another problem i want to know the dim from a list does it work with dim({L1}???

You cant get like how many numbers it got

You cant get like how many numbers it got

There is no command like this but it is not that difficult to code in a subroutine. Assuming your list doesn't include any zeros just do this
_______________________

Fill(L1,711,0)
.this at the very beginning of your program

...
your code here
...
Return
.End of your code

Lbl Dim
0->r2
{r1}
While
 r2++
 {r1++}
End
Return r2

Then using Dim(L1) (with an uppercase D) should return the number of elements "in" L1 (if I didn't do any mistakes)
