The part of my post that you snipped was talking about a program that
contained multiple intercommunicating tasks in a Rate-monotonic system
using a custom frequency-based scheduler. Are you saying that it is
possible to write perfectly portable code in COBOL, Fortran, or C that
can do that?
As near as I can puzzle it, you will need at the bare minimum support
for multiple threads of control within the language. COBOL, Fortran and
C do not have such a concept. Of the languages that can do this, to my
knowledge only Ada and Java are widely available. But I think even Java
is not available for vxWorks. Even if it were, I'm not sure Java threads
have all the features we'd need.
