zork-fortran

This is a source file distribution for the game dungeon as implemented
in f77 for Unix(R) systems. It is based on the game dungeon as
distributed on a DECUS tape, circa 1980. It has been converted from
the original DEC FORTRAN into something that is palatable to Unix f77.
See the file "History" for some revision history and credit to those
whose efforts have made this possible.

Checkout the Makefile and adjust it to fit your system. The only
things that should really need tweaking are the directory definitions
and the "-D" defines. There is an example for both large address
machines (e.g. Vax) that get the complete game and small address
machines (e.g. Pdp-11) that get a modified game with minor functionality
missing (to get it to fit). Also edit the include file "files.h" if
necessary.

All of the f77 files end in a '.F' extension to force f77 to invoke the
C preprocessor for the #include files and #ifdefs. Most of the #ifdefs
are for the PDP version (default non-pdp) and for debug (default off).

Except for DTEXT.DAT, all files in the distribution kit are ASCII.
DTEXT.DAT is a binary file consisting of 76-byte fixed length records.

This has been compiled and tested on a PDP-11/44 Version 7, PDP-11/70
2.9bsd Vax-11/785 4.3bsd and Sun-3 before the pdp and Vax sources were
merged (see the file "History"). After the merge it was again tested on
the Vax 11-785 4.3bsd.

I/we consider my/our changes to be in the public domain. The original
source, however, is copyright.
