Re: EuOS
I disagree. It would be possible to write much of an OS in Euphoria with 2
conditions:
1. Euphoria is converted into C or Assembly
2. C or Assembly is used where Euphoria is incapable of handeling it
The first is pretty easy, I would think. I have code to process Euphoria
code, so all I have to do is make it convert it.
The second is not all that hard. I have experience with C and Assembly, and
I have been reading a book called Developing Your Own 32-Bit Operating
System, from which I think I could get enough info to write some low-level
routines.
