4 | * Message to the wary: The order of tokens has been | |
5 | * hand optimized and assigned to that all switch statements | |
6 | * are implemented by a casel instruction on the VAX. | |
7 | * there are 4 switch statements that have to be worried about: | |
8 | * l) Per character switch in the character scanner (scan_dot_s) | |
9 | * 2) Per token switch in the buffer manager (yylex) | |
10 | * 3) Per keyword switch in the parser (yyparse) | |
11 | * 4) Leading token switch for argments to opcodes | |
12 | * | |
13 | * You can't just add new tokens willy-nilly; make sure that you | |
14 | * add them into the proper order! | |
