37 /*   ADVENTURE -- Jim Gillogly, Jul 1977
38  * This program is a re-write of ADVENT, written in FORTRAN mostly by
39  * Don Woods of SAIL.  In most places it is as nearly identical to the
40  * original as possible given the language and word-size differences.
41  * A few places, such as the message arrays and travel arrays were changed
42  * to reflect the smaller core size and word size.  The labels of the
43  * original are reflected in this version, so that the comments of the
44  * fortran are still applicable here.
45  *
46  * The data file distributed with the fortran source is assumed to be called
47  * "glorkz" in the directory where the program is first run.
48  *
49  * The original FORTRAN version can be found at
50  * <URL:ftp://ftp.gmd.de/if-archive/games/source/advent-original.tar.gz>.
