SuperCharger Disk BASIC supports modular Atari 2600 programs up to 2 MB in size with variable sharing.

Classic BASIC with line numbers can be used like in the simple science text book examples from the 80's.

Code: Select all

0 if g=0 then for x=18 to 239:virtualworld(x)=0:next x else f=f+1:goto 2:rem ini
1 for x=0 to 9:g=g+10:rowcolors(x)=g:next x:x=10:y=5:h=1: rem initial dir right
2 if f<4 then scrollvirtualworldtoggle=0:return else scrollvirtualworldtoggle=1
3 if joy0left=1 then e=1:h=0:i=0:j=0:AUDC0=8:AUDF0=BITIndex:SUSTAINFORFRAMES=15
4 if joy0right=1 then h=1:e=0:i=0:j=0:AUDC0=6:AUDF0=BITIndex:SUSTAINFORFRAMES=15
5 if joy0down=1 then i=12:e=0:h=0:j=0:AUDF0=y*3:AUDC0=15:SUSTAINFORFRAMES=15
6 if joy0up=1 then j=12:i=0:e=0:h=0:AUDC0=3:AUDF0=y*2:SUSTAINFORFRAMES=15
7 x=x-e:x=x+h:l=i/12:y=y+l:l=j/12:y=y-l:BYTErowoffset=BYTErowoffset+i:rem TRON!!
8 BITIndex=BITIndex-e:BITIndex=BITIndex+h:BYTErowoffset=BYTErowoffset-j:f=0
9 if vwpixel(x,y,on)>0 then COLUBK=100:SUSTAINFORFRAMES=100:goto 6:rem Atari VCS


Classic BASIC programs running on the Atari 2600 can be entered in the BASIC10liner.com contest against the VIC-20, Atari 400/800, Apple II, C64, TI-99/4A, Aquarius, TRS-80 and Timex Sinclair home computer systems.

Code free development:
Audio Visual Programs can also be created using only ASCII art and no code:

Code: Select all

Code free programs can also be combined with BASIC code.

SuperCharger Disk BASIC is available on AtariAge here.

I first learned to program with Atari Basic (on my Atari 1200XL) but don't think I want to go back. I did learn a lot of lessons though.

Like instead of using the number 0 in your code, you'd want to set a variable like c0 to 0 and use that instead. It's more characters in your code but a reference to a variable takes up less space than an integer. And back in those days ever byte counted.

Probably as much of a concern with this.

Very cool Atari BASIC is awesome! :)

Yes there are many constraints like that and each DOS program can be only 6K so memory gets used up quickly.

With clever BASIC programming a game can be squeezed into a single module but it's very challenging and the DOS extensions open up a lot of possibilities!

Each new level in a game could be another program - Donkey Kong could have enough room for a 3rd screen just by loading another program with a DOS command.
