#3774 — Some Project Ideas

These are a little bizarre but would be very impressive:

1. A compiler (for C, Pascal, etc) written in Applesoft BASIC. This seems impossible because BASIC is missing features like recursion and structures/records that are normally used for writing compilers. I bet there's someone out there that's smart enough to figure it out.

2. The opposite of cc65, a cross-compiler running in the Apple II that generates executables for Linux/Mac/Windows. Why would you do this? I don't know. We have all these cross-compilers/assemblers that target the 6502 and it just seems a little one-sided.

1) not impossible, recursion can be simulated and there are alternatives to recursion, and you can use other means to store structures.
2) lol! :P

:-) I'm glad someone gets my sense of humor.

IIRC, Microsoft's TASC was written in Applesoft and then bootstrapped...

Someone already wrote a Pascal compiler (well, a Pascal subset) in 
generic BASIC, so it's certainly possible. The compiler compiles to 
P-Code, which is then converted to 8080 assembly.

The Tiny Pascal language appeared in Byte volume 3 #9 through #11:

* https://archive.org/details/byte-magazine-1978-09
* https://archive.org/details/byte-magazine-1978-10
* https://archive.org/details/byte-magazine-1978-11-rescan

  I remember looking at it back in the day, and it seemed doable to 
convert it to Applesoft, but I never got around to it (and I was more 
interested in full compilers, rather than a compiler to a virtual 
machine). Plus, I already had bought Kyan Pascal.

Plus, for all the proting work, Tiny Pascal lacks a lot of features. All 
you get is integers and integer arrays. No records (aka structures), no 
floats, no Strings, even.

There is an assembler written in basic in Nibble magazine to create ML code from source.  It uses ML routines to speed up searches and so forth.

Doing the same for C or Pascal should be just as trivial.

#4048

I typed in BASIC.ASSEMBLER from nibble  by.hand and it was my first assembler.  I wrote a platform game "engine" that used the text screen for "graphics" and drivers.to position a stepper motor connected thru parallel card and driver(power) chips

Then it was on to Merlin because my programs got bigger and
.basic.assembler took too long a
 time to operate

#4050

I like HyperC.  It uses none of Applesoft Basic.  It uses SANE for floating point numbers.  It has support for 65802/816.

Cheers and Happy Holidays!
