| 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! |
