Grammars

The Grammar of a computer language is an essential part of parsing a computer language. The most common way to store a Grammar is to use the Extendend Backus Naur Format (EBNF named after John Backus and Peter Naur). The EBNF of most language are available on the internet, but are not complete. To use these grammars for parsing a complete application for translation purposes it is almost often necessary to make additions/changes, because:

• An absolute grammar does not exist and should not be made.
• The grammar should fit to the solution it is intended for.
• Programmers have their own style. So no computer program is written in the same manner.
• Platform (or other) specific language implementations.

For the translation of a computer language into another at least 2 different EBNF's are necessary. One is used for the parsing process, the other as a template for/definition of the destination language.
