/*
 *      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!
