UNIX Timesharing System No, they aren't generally available, at least not as originals. I personally used Ultrix and AT&T FORTRAN manuals when hacking up the shell scripts. They are both hacked versions of the UTS manuals (the AT&T version less hacked, and somewhat less useful). I've use the thing to compile up simulation software for relativistically invariant P-P, P-N, and N-N collisions, and to apply physical models as the soloution to a set of 13 irreducable Feynman-Dyson diagrams as part of a theoretical confirmation for experimental data regarding the energy range of the carrier of the weak force (Dr. Jay Phippen's work). The resulting code on a Sun SS2+ was facter than the native FORTRAN on a VAX 8800 with vector processor by about a factor of 10, and the output was identical, once I hacked the random functions in for the Montecarlo for the event generator (they are missing from the FORTRAN library that comes with the package). > (I have the Bell Labs CSTR 149 document, but this covers f2c's internals > rater than its usage.) It's pretty vanilla UNIX F77. I believe there are version of the UTS documents still available from UNIX Press. If you had asked me two years ago, I could have sent you an old copy. 8-(. If you can dig up an old Ultrix FORTRAN manual, you will have pretty much what you need.
