                    System Libraries for Fortran Users

     F77plot is an interface library which allows f77 users to  access
     the  UNIX  graphics routines; see "help f77 plotting" and "man 3f
     plot" for more information.

     The f77 system libraries provide the standard Fortran I/O facili-
     ties  and mathematical intrinsics; in addition there is a variety
     of mathematical routines, bit manipulation  routines,  etc.   See
     "man 3f intro" for a description of the non-standard routines.

     IMSL and NAG are large libraries of numerical routines.  They are
     not  part  of  the  standard Bell Labs or Berkeley distributions;
     rather each site acquires them independently.   Check  with  your
     system  administrator as to whether your site has either of them.
     See "help f77 imsl_lib" and "help f77 nag_lib" for more  informa-
     tion on those libraries.
