We are only >interested in software market realities and how this impact DoD systems. I believe Dr. Batsell has just elucidated a good point. His comments support the general case that Ada MUST be used wherever economically possible. It doesn't take a rocket scientist to figure out that proliferation of "specialized" languages for "mainstream" software development will drive up long-term costs like crazy. This is the very reason we are required to use Ada. My company uses Ada for their large, distributed simulations (including the B-2 simulator and the Space Station simulator). I have serious doubts that a research toy like SIM++ could stand up to the weight or the requirements of such "industrial strength" systems. Mind you, SIM++ has some interesting applications for small simulations, but hardly represents the maturity of Ada. I believe there is a place for "specialized" languages, such as SIM++ (or DRAGOON :-), but to advocate their appearance in fielded systems is tantamount to unraveling the LONG-TERM strategy of the DoD. Now, I'm sure Greg would like to pipe in about "economic models", to which I'm not likely to argue (much). The bottom line is, the "best tool for the job" is usually Ada, even if it doesn't look like it in the next three years. But, hey, most of are Americans, right? That means we can't see beyond the current quarter for projections, much less the fiscal year. :-) (Carefully notice the attached smiley). -- -Comments above aren't neceessarily the opinion of the SEI, AJPO, or CAE-Link- David Weller | Have you hugged your DRAGOON lately? ----I'm the Ultimate International Masochist: I speak Ada AND Esperanto!-----
