9C The following small segment of Dungeon (the adventure that became the
10C commercial hit Zork) causes an internal error in f771.  The platform is
11C i586-pc-linux-gnulibc1, the compiler is egcs-ss-970821 (g77-GNU Fortran
12C 0.5.21-19970811)

29C Here's the FORTRAN code, it's basically a single subroutine from subr.f
30C in the Dungeon source, slightly altered (the original calls RAN(), which
31C doesn't exist in the g77 runtime)

33C RND - Return a random integer mod n
