Ah ok then. In BASIC, what happens is that Sub(Str1,2000,128) is about half a second slower than Sub(Str1,0,128).

Ya, but that's just because it starts at the beginning of the string, searches for the start, then displays it, right? So longer the string the more time it takes...well I guess further into a string you want to start at I guess I should say.

Knowing ASM, I'm pretty sure the size of a string makes no difference--TI would have to really screw up for string size to matter.  But it's always a known fact that that more computations the calculator has to make, the longer things take.  You'll notice the difference when you graph Y = 1 and Y = sin(cos(tan(X^100X)))

Well I didn't mean the size of the string is what effects the speed. It's where in the string you're starting from. Like DJ said, if you have a string with 2005 tokens in it you will notice a speed difference between sub(Str1,1,5 and sub(Str1,2001,5.  So the further inside the string you're trying to start from the longer it will take to display it or find it.

Oh, I didn't notice that.  Okay, TI screwed up

I definitively think they did. Further inside the string it's really really slow when the string is long. When people make scrolling RPGs, they add a For loop that artificially slows down the game when scrolling at the top of the map, to equalize the overall speed.

As long as you avoid using Sub(, Correlation handles the rest to make a fast program.  You just have to follow the manual and use the right code--not hard, just different techniques.

Now that the manual is done, and now that the font compilers are ready, back to the coding.

Here's a tribute to Sam Heald.  No source code I'm afraid, but you have my word that this was done completely in Correlation.

Awesome, looking even more useful! I wonder if anyone'll port an actual Mario game to BASIC with this

I finished the code for wrapping text that falls off-screen, so here's a screenshot for Metroid.  This time, I've also attached the font and the code that I used.  The first character of the font is assigned to the character "A" as it will be for many screenshots to come.

Pause

How long does it take to render?

You know, I'm not sure.  I plan to time it pretty soon, probably after I finish negative coordinates.  For sure, though, it still runs faster that TI routines
