Kill "Done"
Kill the pesky "Done" at the end of your BASIC program by entering the following code as last line:

Using Complex numbers
Utilizing complex numbers to minimize variable usage:
Complex numbers have the following properties:
-Positivity/Negativity or real number (boolean)
-Integer part of real number
-Decimal part of real number
-Positivity/Negativity of imaginary number (boolean)
-Integer part of imaginary number
-Decimal part of imaginary number
commands to get these values:
-real( (ok, xLib may interfere with this, so this is unusable while also using xLib)
-imag(
-iPart(
-fPart(
using these properties of complex variables in the right way can substitute the usage of six real variables!

this waits until you press ANY key then continous on, useful for talking in your game

Another trick I like I used in GQES to boost speed:c1-->
| CODE |
| ec1Repeat (long keypress condition here) Repeat Ans (grayscaling code here) getKey End End Ans->Kc2 |
ec2The long condition slowed down the loop on every cycle. This way fixes that.

I discovered an interesting flaw in the interpreter. It only checks the condition on Repeat at the repeat's End. Thus a program, though memory erroring, like the following would cause no syntax error:
Repeat -----------------+++-++++++++-
Post by: Dragon__lance on June 07, 2006, 03:20:00 pm
i have a question though, according to my understanding, the BASIC interpreter converts each line of BASIC code into ASM, checks for errors, and then executes it. If it is like this, can't there be a program that just first automatically converts the BASIC into ASM, thus gaining speed?

I only have a simple understanding of asm...

Good luck trying to take advantage of this undocumented trick. XD

Vladic, just because they can only afford an 83+ doesn't mean that a person should be excluded.
One interesting unknown fact is that finance variables run faster then even ans. I often use finance variables in phisics engines or other programs that need every slight speed boost they can get.

The finance APP (the one you can't delete) contains variables made specifically for that app that you can use in normal programming. You can always use them because you can't get rid of the finance app. They are faster because they are programmed differently than the other variables (which use built-in bcalls). These are processed by hooks (like xLIB) and executed from the APP instead of the OS's horrible methods.

If you want your programs and games to be smaller, don't use lowercase letters for the text unless it's really necessary. Lowercase letters and some other symbols are like Unicode on the calc and they take up two bytes for each one you use. If you have lots of text in your program, and you're using lowercase, try making it all uppercase and see how many bytes you save (doing this has saved saved up to 75% of space per program on my calc...)
This post is 588 bytes long. If you put this in your calc, it would be double that unless you made it uppercase.

Output(X,Y,"I%"
Output(X,Y," ")
to output a % at X,Y+1 for loading screens because that is the only %sign on the calc (I% is a finance variable)

when/if you use the homescreen for a graphical game without "smooth" scrolling. you can convert what you would output into a string and then use that as an almost screen buffer. if you do this it actually will shorten your code. all you do it redraw the string before you update the position. Well im not sure if it will shorten everyone's code but it defenitely shortened my perhaps unoptimized code a few bytes. plus you can use sub(str,(a-1)*16+B) as hit detection, i think its faster than matrix hit detection.
Edit by Netham45: part of your code was showing up as a smiley.

It's been there all this time and no one ever knew... We knew there was a routine deep in the OS to do it, but no way to call it outside ASM...
