Concern 2. >And as far as your last statement, what kind of rope are you smoking, anyway? While Paul writes, Concern 3. >I don't know where you picked this information from, but you are hopelessly >wrong. We use our own products extensively. Concern 1: As to a specific problem with the Alsys compiler, I will use an example of one that cost me over a month of testing on a project. The manner in which Alsys implements a timed entry for SCO Unix in is incorrect. If the timed entry call is not used (i.e. due to a gaurd clause) over the course of 38 to 50 hours, it crashes the program with a CONSTRAINT_ERROR. This is not the only compiler bug on the Alsys Ada compiler I have found (their implemenation of standard input and output files does not work either) but it is certainly the most costly I have seen. Yes all compilers have defects, but the magnitude of the defects, the kinds of defects, and the compiler vendors response to defects says something of the reliability and usability of the compiler. Concern 2: Resorting to insulting to me does not change the fact that one of Alsys's own people DID say they did not use the Alsys Ada compiler. Concern 3: Paul, I never said that Alsys does not use its own products. From what I understand, for example, Teleuse (sp?) is quite a good GUI product put out by Alsys, and I am certian that Alsys has other fine products that are thouroghly used internally and externally to Alsys. I used a specific example (the Ada compiler) and meant no reference to any other products. If one was perceived, I am sorry. Jon.
