I think that Basic is more suited for RPGs and games that need large amounts of easily accessible memory and variables, and not necessarily speed, but Axe is all about speed, good for arcade games and similar things.

To display a list, you have to write your own routine.

Yeah, that should work... as a new item is introduced to the game, just increase the size of length(L1) and make sure you have EVERY item built into the game so that when the length increases, it knows which item to add to the menu.
For instance, at the beginning, maybe the character can only use potions
Then, to add apples to the menu, all you have to do is
or for all three items, store 3 to the length.

Then to remove items from the menu, if you had all three items, but didn't want feathers anymore, just use 2->length(L1) and the feathers are gone

I don't entirely understand the question, but you can write one past the length of the list in TI-BASIC, and it will add another element for you.  Does that help?

If you want something like this:

Where it shows how many potions you have, tell me.
You can use a custom menu, or a manipulated OS one

yeah that actaully looks really good was the potions menu accessed through a menu that took it to its own specific menu and sorry if by menu I actually mean and/or list
If you want something like this:

Where it shows how many potions you have, tell me.
You can use a custom menu, or a manipulated OS one

output allows you to display something at a certain point
for example:
:output(1,1,"hi"

will make it appear at point 1,1 on the screen, or the upper left corner!

Okay, here is the code for a simple menu:

Try that, should work okay
Tell me if you have questions, or if it doesn't work
