| 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! | |
