Writing a compiler in assembler sounds difficult. Apart from the first compiler one would think that compilers should be written in compilers? Sure Slang already exists, but extending a program this big, written in assembler could be a pain in the ass. How about bootstrapping Slang in itself? :-) we...

Is the sourcecode avaliable? I may be blind but I didn't see it at the mainpage.

What is it written in? ( cc65? )

Sorry, I ment i read the disassebled code for the examples on the site.

While it's possible to hand-optimize a smaller project when disasembled, I figure it would be quite difficult to quickly get a grasp of how the code relates to the source if the project grows large.

Just looked quickly at the slang page, and just tought "wow, I've been thinking about this". Looked at the examples and the languague reference and the output (assembler-code) and it looked quite nice. I will return to this site and read some more soon. My thoughts about compilers so far h...

I'm so glad I'm not the only one thinking about compilers for 6502. I've been reading about compilers / compiler generators / lexers / parsers etc. for quite a while now and I've been doing a lot of "homework" on that subject for quite a while. I've written quite a cool lexer/parser in Fre...

I use the C2N232 for all VIC work. Almost everything i do is crossassembled or compiled (65CM) on the PC, but i use C2N232 to test run on a real VIC20 while working (instead of VICE) It also works great when flashing my PETRAM because the transferrate is high ( 38400 if i recall right ) so loading 1...

I've got an CBM disk-collection from some dude when I bought all his old Commodore stuff in the late 90ies. Guess his parents was rich becoz all his discs was Maxell Gold with a lifetime guarantee. When i started converting all my floppies to .d64-files these diskettes ALL WORKED and they had not be...

Hi everybody! Does anybody more than me own a PETRAM expansion for the VIC20? I'm asking because I've been thinking about rewriting my fullscreen assembler VASM for PETRAM. As PETRAM puts flashable rom @ $a000-ffff I hope to make an CART+SYSTEM image of it + KERNEL ROM and stripping away most of the...

>Ok, I probably was wrong, but I have a strong feeling FOR-NEXT can do >stupid things with the stack, in particular in combination with GOSUB. You're absolutely right about that. The FOR keyword uses the stack to point out the start of the loop for the NEXT keyword. GOSUB uses the stack for return p...
