Need moar variables...
« on: October 18, 2010, 05:48:38 pm »
Is there a way to access moar variables in Axe?  Like the Finance variables for BASIC, or something like lists?  or can the Axe lists do this?  if so, I need to figure out how to do it.  ;)

if you need more variables, there are several option open to you.  In portal, i use memory locations for many variables.  Like {L1+13}r is the same speed and takes the same amount of memory as the variable A.

{address}r is the same as a regular variable.

Ex:
{L1}r
{L1+8}r
{L4}r
{oA}r (This is the same as just doing A)

Good luck. :)

could you elaborate on that a bit?  How would you know which ones are usable?

you can use any portion in the free RAM areas L1-L6 as your own variables.

I see, so if I did 5->{L1}, and then wanted moar variables, I would do 42->{L1+1}  but if I wanted to store a two byte number, would I do 256->{L1+2}r?

yes. be careful about it though. if you do 256->{L1+2}r, make sure you don't try to make a variable at {L1+3}, because this is already being used by the two byte variable at L1+2

L1.  Read up on it in the commands list if you want more info. :)

And don't write beyond the limits of L1.  That is called an overflow error and strange and terrible things will happen to your calculator as a result.

yeah... just don't use more than 700 bytes worth of variables and you'll be fine (like you even need 350 variables)

L1. In that area of safe RAM (the 54 bytes before where L1 points) is where the built-in 27 variables reside, too.

Note that in some cases, using L2 might cause incompatibility with MirageOs for the people that still uses it. It conflicts with Mirage's interrupts.

I personally use L1 most of the time.

Btw with L4, it talks about corruptions with the Archive/Unarchive. Does it means the Axe archive/unarchive commands or the entire TI-OS after exiting your program?
