Gentee Language in BNF

You can use ANSI character set from 0 to 255 in a source code. ANSI character set from 32 to 128 are specified in the diagram defined above, other characters are represented in hexadecimal notation, for example 0x09 - a tab character. Some preprocessor commands are not shown in these diagrams.
