Used by the routines at PARSE_COMMAND, PARSE_AND, PARSE_VERB, PARSE_PREPOSITION and PARSE_ADJECTIVE.
From the pointer in TOKEN_POINTER, which it moves on. The previous position is kept in VARIABLES, which is what the main loop echoes back when a word is not known, and the previous class in LAST_CLASS, which PARSE_IN looks at.
