However, it doesn't work on my 83+ (1.15); I just get a "?".

Transferring the creature via link cable wasn't fruitful (ERR:VERSION).

Depending on the OS version, some tokens aren't available.

That's interesting. It's a lot like the "Text(-1, ..." thing. I wonder what other secret functions TI put in the OS.

Whoa, that means my calculator is around 7 years old...
Just so you guys know, there *are* in fact people out there with OS versions as old as 1.12 that don't plan on upgrading any time soon. This means that the 1.15 and 1.16 tokens should be used with care, and any time you do use them, at least put a note in the readme/program description about the OS requirements.
Also, all unusual tokens, up to and including even the relatively common lowercase letters, are semi-incompatible with the TI-83. By "semi-incompatible" I mean that if you transfer a program with them from the computer it will be fine, but calculator-to-calculator transfers will crash with an ERR:VERSION if the program contains these tokens. |

| I tested the Circle( thing on OS 1.12, so I think it's safe to say it works on any. :biggrin: |

Over and done with.
You can save four bytes with one of the following instead:
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]ZStandard
84→Xmin
52→Ymin
ZInteger
ZDecimal
90→Xmin
58→Ymin
ZInteger
ZTrig
88→Xmin
58→Ymin
ZInteger
[post="104858"]<{POST_SNAPBACK}>[/post] Remember this? To get the window settings to[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]
Xmin=0
Xmax=94
Ymin=-62
Ymax=0
I tweaked Weregoose's:[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]
ZStandard
84→Xmin
52→Ymin
ZInteger
A bit to get:[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]
ZStandard
84→Xmin
-72→Ymin
ZInteger
Only adds a byte  . |

if you need to Text a " on the graphscreen, you can do Text(Y,X,'' (two appostraphes) ' is found by pressing 2nd + Apps and then it's the second one down.
This only works with Text(, not Text(-1... or Output( |

Trick that can help you to save 1 byte each time "100" appears :
Replace "100" by "e2"
( "e" is the little E ) |

maybe you could get rid of  [COLOR=purple]goto and lbl's even though I use them in my programs |

I haven't read everything (Obviously!) but these are some I found:
rand can be used to store something to, as it turns out you can give it a 'seed' number, when you do 0->rand the outputted values are always the same after every 0->rand (or any other number)
Be carefull though, sometimes, when you run specific asm progs, they mess with the calcs random number generation and rand keeps spitting out zero's... Anyone knows how to get around it?
you all know the trick if you want to add/subtract only if a condition is true, but wouldn't it be fun if we could multiply if a condition was true?
Code:
\\ Do A+1-> if A<100
A+(A<100->A \\ Duh!
\\ Do A*B->A only if A<1000
A*(B^(A<1000->A \\ This works because x^0=1 and x^1=x

I'm glad you know that now, but that's a very old trick known as "booleans". Any true conditional equals 1, any nontrue is 0.
For the second one...that will reset A to zero if it's greater than or equal to 1000. |

| It won't, since B^0 is 1, and A*1=A. |

An other trick, but it's slower ( a little bit only ) :
Use 4{^-1} instead of .25 (1 byte less)

| Yeah, but sometimes one byte is worth a decrease in speed (in places where speed is rather unimportant). |

| Super Speler does have a point. Space savers shouldn't just be tossed out because they are slower, although I do think that you should mention if it is slower in the post. |

Which is precisely why I said it  . That, and because I typically program speed-necessary games. |

[quote name='"Cryzz"']\\ This works because x^0=1 and x^1=x[/quote]
Though I think you can leave out the braces because ^ has a higher precedence then *
Thus:
Code:
\\ Do A*B->A only if A<1000
AB^(A<1000->A \\ This works because x^0=1 and x^1=x
Should work, right? |

Sorry, it just seemed like you were presenting as though nobody knew it :blush:.
As for your latter, yes, since the calc follows order of operations, it will multiply the exponent of B before it multiplies by A. IIRC. |

*bump*
This probably isn't new, but here goes...
If you store frequently used code to a string, you can recall the string into a program as a sort of "copy-and-paste" function. However you have to go through menus to get to the string, not to mention delete the quotes.
So store your three most frequently used pieces of string into those variables, u, v, and w. Recalling those doesn't make quotes, and it's faster than getting it from a string.
If you want a chunk of code, go grab that ASM subroutine from PyroEdit 4.0, PRGM2STR. Put the program name in Ans, run the subroutine, then store Ans to one of those vars. Done! A program now entirely contained in a single variable.
I've been using this a lot lately, just decided to throw it out there. Terrific for a lot of small pieces of code you use a lot. |
