/*   ADVENTURE -- Jim Gillogly, Jul 1977
 * This program is a re-write of ADVENT, written in FORTRAN mostly by
 * Don Woods of SAIL.  In most places it is as nearly identical to the
 * original as possible given the language and word-size differences.
 * A few places, such as the message arrays and travel arrays were changed
 * to reflect the smaller core size and word size.  The labels of the
 * original are reflected in this version, so that the comments of the
 * fortran are still applicable here.
 *
 * The data file distributed with the fortran source is assumed to be called
 * "glorkz" in the directory where the program is first run.
