TI-BASIC Q&A

[parserp]

Ok, screen dimentions were wrong

* epic7 adds zstandard

That will work, right?

yes, if you want a 10*10 window.

I just wan't to keep that game and have it work for historical reasons

[njaddison]

What kind of Ti-Basic are you guys talking about? nspire basic, which I know alot about, or ti-84 basic, which I know almost nothing about?

[epic7]

83 and 84 basic

yes, the latter. (83 BASIC)

EDIT: ninja'd! and lost the game!

[epic7]

Ninja'd

I think there's an nspire basic somewhere though.

I'm reworking my Windows 85/86 program, and would like to know if there is any way to shrink this code:

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7

0→x Repeat x getKey→x End If x≠[a getKey value] Goto [label]

Is it possible? How would this be done?
It was originally TI-85 code, but it works (and preferably needs to work) from TI-82 to TI-86.

[parserp]

Code: Select All | Copy To Clipboard

1 2 3 4 5

Repeat GetKey End If Ans≠[a getKey value] Goto [label]

that should work...

Also Parser that code would not work at all, or at least not do the same thing.  It only checks for a key once, and if there is no key, the loop will go forever.

ah yes, fixed (I think)

I've forgotten to say that the returned key may need to be stored (many complicated reasons [simulated keypresses over link on 83+]) but that's an easy fix.

Parser: This code only seems to work on the 83 series; it returns 0 for Ans on the 85 series. It is about as small as it gets without starting any contests.

Builderboy: That code works well for the 85/86; I realized the 0→x part was unnecessary as Repeat doesn't test before running.

Thank you both for your help!

I never learned what 'Tangent' and 'sub' do in BASIC. Could someone enlighten me?

[Builderboy]

You should check out TiBasic Developer, they have well documented pages on pretty much every TiBasic command there is!  Just type whatever command you are curious about into the search bar and learn

[Deep Thought]

sub returns a substring and is one of the most useful commands there is. Tangent draws a tangent to a curve. As Builderboy suggested, look on TI|BD for usage info (links right in this post ).

I'm a real super super super beginner, but how do you check if a certain key is pressed?
Also are there arrays in BASIC?

[Yeong]

instead of array, we have list (element start from 1, not 0 ).
for key check, we use getKey.
