C  CURRENT LIMITS:
C	750 TRAVEL OPTIONS (TRAVEL, TRVSIZ).
C	300 VOCABULARY WORDS (KTAB, ATAB, TABSIZ).
C	150 LOCATIONS (LTEXT, STEXT, KEY, COND, ABB, ATLOC, LOCSIZ).
C	100 OBJECTS (PLAC, PLACE, FIXD, FIXED, LINK (TWICE), PTEXT, PROP).
C	 35 "ACTION" VERBS (ACTSPK, VRBSIZ).
C	205 RANDOM MESSAGES (RTEXT, RTXSIZ).
C	 12 DIFFERENT PLAYER CLASSIFICATIONS (CTEXT, CVAL, CLSMAX).
C	 20 HINTS, LESS 3 (HINTLC, HINTED, HINTS, HNTSIZ).
C  THERE ARE ALSO LIMITS WHICH CANNOT BE EXCEEDED DUE TO THE STRUCTURE OF
C  THE DATABASE.  (E.G., THE VOCABULARY USES N/1000 TO DETERMINE WORD TYPE,
C  SO THERE CAN'T BE MORE THAN 1000 WORDS.)  THESE UPPER LIMITS ARE:
C	1000 NON-SYNONYMOUS VOCABULARY WORDS
C	300 LOCATIONS
C	100 OBJECTS
