Allman 5/76 (U.C. Berkeley) with help ** from Jeff Poskanzer and Pete Rubinstein. ** ** I also want to thank everyone here at Berkeley who ** where crazy enough to play the undebugged game. I want to ** particularly thank Nick Whyte, who made considerable ** suggestions regarding the content of the game. Why, I'll ** never forget the time he suggested the name for the ** "capture" command. ** ** Please send comments, questions, and suggestions about this ** game to: ** Eric P. Allman ** Project INGRES ** Electronics Research Laboratory ** Cory Hall ** University of California ** Berkeley, California 94720 ** ** If you make ANY changes in the game, I sure would like to ** know about them. It is sort of an ongoing project for me, ** and I very much want to put in any bug fixes and improvements ** that you might come up with. ** ** FORTRASH version by Kay R. Fisher (DEC) "and countless others". ** That was adapted from the "original BASIC program" (ha!) by ** Mike Mayfield (Centerline Engineering). ** ** Additional inspiration taken from FORTRAN version by ** David Matuszek and Paul Reynolds which runs on the CDC ** 7600 at Lawrence Berkeley Lab, maintained there by ** Andy Davidson. This version is also available at LLL ** and at LMSC. In all fairness, this version was the ** major inspiration for this version of the game (trans- ** lation: I ripped off a whole lot of code). ** ** Minor other input from the "Battelle Version 7A" by Joe Miller ** (Graphics Systems Group, Battelle-Columbus Labs) and ** Ross Pavlac (Systems Programmer, Battelle Memorial ** Institute). That version was written in December '74 ** and extensively modified June '75. It was adapted ** from the FTN version by Ron Williams of CDC Sunnyvale, ** which was adapted from the Basic version distributed ** by DEC. It also had "neat stuff swiped" from T. T. ** Terry and Jim Korp (University of Texas), Hicks (Penn ** U.), and Rick Maus (Georgia Tech). Unfortunately, it ** was not as readable as it could have been and so the ** translation effort was severely hampered. None the ** less, I got the idea of inhabited starsystems from this ** version. ** ** Permission is given for use, copying, and modification of ** all or part of this program and related documentation, ** provided that all reference to the authors are maintained. ** ** ********************************************************************** ** ** NOTES TO THE MAINTAINER: ** ** There is a compilation option xTRACE which must be set for any ** trace information to be generated. It is probably defined in ** the version that you get. It can be removed, however, if you ** have trouble finding room in core. ** ** Many things in trek are not as clear as they might be, but are ** done to reduce space. I compile with the -f and -O flags. I ** am constrained to running with non-separated I/D space, since ** we don't have doubleing point hardware here; even if we did, I ** would like trek to be available to the large number of people ** who either have an 11/40 or do not have FP hardware. I also ** found it desirable to make the code run reentrant, so this ** added even more space constraints. ** ** I use the portable C library to do my I/O. This is done be- ** cause I wanted the game easily transportable to other C ** implementations, and because I was too lazy to do the doubleing ** point input myself. Little did I know. The portable C library ** released by Bell Labs has more bugs than you would believe, so ** I ended up rewriting the whole blessed thing. Trek excercises ** many of the bugs in it, as well as bugs in some of the section ** III UNIX routines. We have fixed them here. One main problem ** was a bug in alloc() that caused it to always ask for a large ** hunk of memory, which worked fine unless you were almost out, ** which I inevitably was. If you want the code for all of this ** stuff, it is also available through me. ** *********************************************************************** */ jmp_buf env; __dead static void usage(const char *av0) { errx(1, "Usage: %s [-fs]", av0); } int main(int argc, char **argv) { int ch; /* Revoke setgid privileges */ setgid(getgid()); /* Default to fast mode */ Etc.fast = 1; srandom((long) time(NULL)); while ((ch = getopt(argc, argv, "fst")) != -1) { switch (ch) { case 'f': /* set fast mode */ Etc.fast++; break; case 's': /* set slow mode */ Etc.fast = 0; break; #ifdef xTRACE case 't': /* trace */ Trace++; break; #endif default: usage(argv[0]); } } if (optind < argc) usage(argv[0]); printf("\n * * * S T A R T R E K * * *\n\n" "Press return to continue.\n"); if (setjmp(env)) { if ( !getynpar("Another game") ) exit(0); } do { setup(); play(); } while (getynpar("Another game")); fflush(stdout); return 0; }
