Capt. Quirk,

Like Jon said, sx/b 2.0 is not multithreaded. Pjv's multithread model is not easy to implement
in basic because it requires many resources (think local stacks to preserve context). Like Jon,
I too think that it is too difficult to ever make that happen.

Sx/b 2.0 does support tasks and these behave like many basic's ON INTERVAL GOSUB statements.


The framework Jon mentioned is a work in progress. It uses some sx/b 2.0 features but is mostly
encoded in assembly. That's probably also the reason why Jon has a hard time to understand
that code. My goal is to put it in library files with sx/b wrapper functions so you just
need to include a library and call some sx/b function. Biggest problem still is how to filter out
unused pieces of library code. That should be done in a consistent way so that you can easily
write your own libraries as well. My libraries currently are targeted towards installable VP code,
but you can also have pure sx/b libraries for math functions or whatever.
The design of library files is independant of sx/b compiler design, so when sx/b 2.0 is released,
I can post the framework so the library design can be discussed and improved.
