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!
