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

| C Here's the FORTRAN code, it's basically a single subroutine from subr.f |
| C in the Dungeon source, slightly altered (the original calls RAN(), which |
| C doesn't exist in the g77 runtime) |
| C |
| C RND - Return a random integer mod n |
| C |
| INTEGER FUNCTION RND (N) |
| IMPLICIT INTEGER (A-Z) |
| REAL RAND |
| COMMON /SEED/ RNSEED |
| |
| RND = RAND(RNSEED)*FLOAT(N) |
| RETURN |
