Appvars, and referring to a certian point in one?

[boot2490]

Currently, I am using OS lists, so they are extremely large. I would like to use an appvar instead, to save space. So basically, I want to store a list in an appvar, and through AXE, refer to a certian entry in that "list" to be used in calculations. Is this possible?

[leafy]

To create an appvar, use

GetCalc("appvNAME",SIZE)->POINTER

Then to access bytes of that appvar, use:
{POINTER+ENTRY}

check out the axe manual for more stuff on that.

When you say you want to store a list in an appvar, do you mean you want to store TiOS List's inside of an appvar, or just store a list of 16bit numbers in an appvar?

[boot2490]

I want to store numbers, in sequence, to be reffered to later, but without filler like in OS lists.

Then leafy's code should do what you want.  To access an Appvar that has already been created, just do:

Code: [Select]

GetCalc("appvName")->Pointer

[boot2490]

so the pointer is a number? and the appvar name can be typed in?
so, in

GetCalc("appvarNAME",SIZE)->POINTER

Then to access bytes of that appvar, use:
{POINTER+ENTRY}

I would type:
GetCalc("appvarAXELIST",20)->1
wait, what is pointer+entry? I'm still confused.

You wouldn't type in 'appv', as that is a token you get access to by pressing [2nd] and then [8].  GetCalc() is a command that returns a pointer, where that pointer is the location of the start of the appvar.  Your code would look something like this to create the Appvar.

Code: [Select]

GetCalc("appvAXELIST",20)->P
The variable P now holds the location of the start of the appvar.  To access the first byte of the appvar, you would do

Code: [Select]

{P}
To access the second byte of the appvar, you would do

Code: [Select]

{P+1}
And so on

How big do you want your numbers to be? If you only want them to be between 0-255, You can hold one number per byte. Otherwise, you will need 2 bytes per number (0-65535).

154->{P+12} will store the number 154 to the 13th byte in your appvar.
24479->{P+17}^r will store the number 24479 to the 18th and 19th bytes in your appvar. The superscript 'r' tells axe to save the number as 2 bytes.
