10: * Message to the wary: The order of tokens has been
11: * hand optimized and assigned to that all switch statements
12: * are implemented by a casel instruction on the VAX.
13: * there are 4 switch statements that have to be worried about:
14: * l) Per character switch in the character scanner (scan_dot_s)
15: * 2) Per token switch in the buffer manager (yylex)
16: * 3) Per keyword switch in the parser (yyparse)
17: * 4) Leading token switch for argments to opcodes
18: *
19: * You can't just add new tokens willy-nilly; make sure that you
20: * add them into the proper order!
