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