Link to my ACTION! cross compiler.

The assembler is progressing. I am currently working of the code
for translating the instructions into machine code. Boy, this is
tedious. An assembler is a lot easier than a compiler, but it is
by far much more boring to write.

Ok, so we don't need another assembler for the 6502. The main
reason for this project is that I need an assembler that I can modify
to my hearts content for use with the Action! compiler I am trying to
write. As of yesterday, I am pretty much ready to start testing
the code that is being generated by the compiler, so I need an
I found documentation on line for
the Atari execcutable load format, which is very simple, thank
goodness, so this is the format I will use to produce
executables. This will also work nicely with the simulator I am
using which will load Atari load formats.
assembler is going to be very simple. I am not planning on any
macros. However, I amy eventually make it so that it will output
linkable modules. But, that is for much later.
The first vwersion has not been completed yet, but I do have the grammar written and ready to go.
It is going to be a context free assembler. Not sure how that is going to work.
Stay tuned for the first posting of the source code.
