I've been paid fairly good wages to write programs in all four languages
that you mentioned (COBOL, PL/I, Ada, and FORTRAN), so I guess I'm
qualified to comment:
I think, feature-wise, PL/I has sufficient capability to write embedded
flight software (which, if you look at the title of this thread, was the
domain of interest), assuming the presence of an adequate support
library. What strikes me as odd is the thought that PL/I is _better_
than Ada for this domain. I can't think of anything in PL/I that I would
want for this domain, that I don't have in Ada.
More importantly, based on the list of targets posted recently for which
PL/I is available, it seems to me that there's not been a lot of work
done to target PL/I compilers to CPUs used in safety-critical flight
applications. Ada compilers , on the other hand, are available for
several appropriate CPUs (16-bit and 32-bit). Not having a compiler
available would seem to be a serious limitation to its use for a
particular CPU/domain :)
I am curious: Is there anyone in Team PL/I that has actual experience in
building (successfully) operational flight control or inertial reference
system software in PL/I? For what airframe? CPU? All my PL/I experience
is on IBM mainframes...
