          turn a true value (exit code of 0) if program currently runs
          on a processor that is indicated by the command name.

               m68k    True if program currently runs on a 680x0.
               pdp11   True if program currently runs on a PDP-11/45
                       or PDP-11/70.
               u3b     True if program currently runs on a 3B 20S.
               u3b2    True if program currently runs on a 3B 2 com-
                       puter.
               u3b5    True if program currently runs on a 3B 5 com-
                       puter.
               u3b15   True if program currently runs on a 3B 15 com-
                       puter.

                       or VAX-11/780.

          The commands that do not apply will return a false (nonzero)
          value.  These commands are often used within make(1)
          makefiles and shell procedures to increase portability.
