The superiority : of BETA embedded in the Mjolner Beta system is just astonishing. And ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ I doubt that there is any computer scientist that will contest the superiority of BETA, it is indeed a superior language. --yet another big snip-- : I conclude the computer scientists cannot see the superiority of : BETA especially because they cannot see that the rainbow has seven : colours. They dictate that the world can be seen just as blue, : or yellow or green according to their biased viewpoints. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Computer scientists do concede the superiority (in design and specification) of BETA. At least my view is not coloured in that respect. However, the reason for the popularity of C++ v.s. BETA are different--- the cons are as follows: BETA: o Has only one implementation which unfortunately is commercial. o As has been already mentioned by JLK, the present beta system's speed is equivalent to unoptimized C or C++. o The Mojlner Beta System (MBS), is unavailable in source form. o The user base is so small that there is no international effort to standardize BETA (like ISO standard or ANSI standard etc) o Most people (one news item also had comments from Mjolner people) use BETA in research environment (including me!). o Atleast one free version of the language must be available preferably GNU GPL'ed, with sources, so that researchers and individuals with low budgets can experiment with the environment and the language. Experimentation in this regard does not mean that individuals must only write end-user-applications, but that the semantics and syntax could be changed, modified etc. I for one will be elated if such an environment was made available--- (not a klugged version of MBS, I mean a full environment __no_bars ). o For a language to find acceptance in market, it must have lots (atleast more than one) implementations of production quality. This is healthy for development. It must have a whole lot of tools based on solid software engineering for development/debugging etc. Beta lacks that level of finesse in its development environment. o For large acceptance, semantic interpreters for popular languages must be provided that can enable a big organization to migrate their existing mamoth applications to BETA without problems. C++: o Is very close to C in which major OS's are written. People feel that apps written in C may run faster on the OS due to existing affinity with C. o Excellent commercial development environments, on almost all OS's and hardware. o Excellent free GNU compilers available that enable development to occurr without suing the pants off poor individual developers. o Standardized semantics and syntax (ISO -- ANSI). o Tools for assisting in migration from other languages etc... -- Greetings, __ N.Sharma@IS.TWI.TUDelft.NL __________/ F c'____---__=_/ Naresh _______________o_____o___________http://is.twi.tudelft.nl/~sharma/
