Windows 16 bits as using the pure Pascal calling convention, that is, the âpush left to rightâ. However, in both case, the invoked procedure clean the stack. Thanks to have noticed about an influence from Mac. I believe this is possible, indeed. -- There is even better than a pragma Assert: a SPARK --# check.

I will later attempt to build a cross compiler Windows -> Mac, and I guess this document gonna be useful to me to try to create Mac applications from Windows (unfortunately, I do not have a Mac to test :( will have to bother somebodies and ask them to test) -- There is even better than a pragma Assert: a SPARK --# check.

"Ada" refers to a standard language definition. It is written in English (there may be translations to other languages available). Various Ada compilers are written in various languages. The GNAT compiler front end is written in Ada; the back end is gcc, written in C; the runtime is written in Ada, with a little bit of assembler for specific machines. -- -- Stephe

That does not follow. If I have a language designed for manipulating databases, that means is is _not_ a good language for implementing a compiler. -- -- Stephe |
