I have increase the performance of my parser by simplifying the lexer and the parser. After I took out the recursion lexing and parsing one token at the time was easier.
My examiner wants me to implement an external C function to improve the speed of the lexer but the lexer is not my concern now. The time that the parser takes is considerable long, compared to the lexer.
More test will be performed over this weekend at the same time I keep growing the grammar which now only fails in 98 out of 568 cases in the grammar.
