The application was robot kinematics, and (briefly), the results were: Ada was easier to code and debug. The Ada development environment (DEC LSE, VMS) was _much_ nicer than the C environment (DEC C - not a very friendly compiler). Also, I was able to code more abstractly in Ada, making the code match the problem statement, which eases debugging. Since this work, I have done other work in Ada and C, and I find I am _much_ more productive in Ada (although some of that productivity comes from VMS vs UNIX). DEC Ada 1.4 was _Faster_ (by about 25%) than DEC C 2.3 (Hip Hip Hooray!!!) (honesty forces me to admit that some of the speed gain came from using single precision - but how do you get C to use single precision?) Verdix Ada 5.5 (on the Sun) was slower (by about 10%) than Sun C 3.2 ( good enough for me) I am interested in publishing this work - can anyone recommend an appropriate journal? Anyone else have similar data? Its time us Ada users spoke up. -- NAME: Stephe Leake TELE: (301) 975-3431 USMAIL: National Bureau of Standards ARPA: leake@cme-durer.arpa Rm.
