I picked up a copy of COTS Journal at the Embedded Systems Conference
last week and it had an interesting article on a company (producing
video monitoring and security systems) that switched from C to Ada and
reaped the rewards.  Their data showed not only that their Ada code
(which took no longer to write, BTW) had fewer errors (1 per 270 SLOC,
vs. 1 per 80 SLOC for C), but that the average bug fix took only 1/12
(!) as long (20 minutes vs. 4 hours).  These two figures work out to a
40-fold (!) improvement in bug fixing time/cost.  This is certainly an
attention-getting figure, much more so than the lower error rate
alone.  Seems like the Ada debug time / SLOC advantage is something
that should be touted more (recognizing of course that other projects
will have different, but presumably not all -that- different, results).
