Multitasking Preview Release
I've posted, as a User Contribution, the 2.5 PD source interpreter
modified for multitasking.
It supports several multitasking API calls.
It has a scheduler built-in to the interpreter.
Instead of the traditional single call stack,
each task has its own call-stack, program counter (i.e. current statement)
and private variables.
By executing task_yield() at any place its code, and at any level of
subroutine call, a task can yield control to the scheduler, and get it
back later. See readme.txt for more info.
Included is a modified version of Language War, converted to use the
new API. I also created a graphical (DOS) demo that shows 4 different
sorting algorithms running in parallel.
For the PD and official interpreters, a major change was/is required in
the way that private data is saved/restored. The Translator should be
simpler.
I don't expect most programs will use multitasking, but it's a
lot of fun where appropriate.
