           sor.

     i386  True if you are on a computer using an iAPX386 proces-
           sor.

     pdp11  True if you are on a PDP-11/45 or PDP-11/70.

     sparc True if you are on a  computer  using  a  SPARC-family
           processor.

     u3b   True if you are on a 3B20 computer.

     u3b2  True if you are on a 3B2 computer.

     u3b5  True if you are on a 3B5 computer.
     u3b15 True if you are on a 3B15 computer.

     The commands that do not apply will  return  a  false  (non-
     zero) value.  These commands are often used within makefiles
     (see make(1S)) and shell scripts  (see  sh(1))  to  increase
     portability.
