I'm working on a new programming environment/interpreter cart for the 2600... Something along the same lines as the Basic Programming cartridge, but with a new language designed from the ground up in parallel with the cart, and with a faster, saner interpreter environment. I'll keep you posted as things develop... but for now here's a sample program:

PROGRAM 'SAMPLE'    READ VAR1;reads the value input on the keypad into VAR1    IF VAR1 = 8:      VAR1+1=VAR1;      ELSE SUB FINISH;"SUB FINISH" basically being a GOTO FINISH SUB FINISH;declares a subroutine "FINISH," kind of a label    DISP 'DONE';like a PRINTEND PROGRAM

Look good? The PROGRAM declaration is pretty superfluous and will probably not make it to the final revision of the language. The aim for this project is to explore the question "What would a long-lost prototype for a sequel to Basic Programming look like?" and also to see how useful of a programming environment an unmodified, unextended Atari 2600 can support. The only peripheral I'll even consider supporting (besides the requisite Atari Keypad) is the AtariVox for saving programs.
