The NAG Double Precision Fortran Library Mark 19 (FLIB619DA), which is a
comprehensive collection of Fortran routines for the solution of numerical
and statistical problems, has been installed in /itl/apps/naglib-19 
for IBM RS6000s.

This implementation is considered suitable for operation on the computer
systems detailed below: 

  hardware:         IBM RISC System 6000
  operating system: AIX v4.1 to v4.3
  Fortran compiler: XL Fortran f77 and f90 v3.2 to v5.1

The libraries are accessible from /itl/links/generic/lib

   libnag.a
   libnag_sh.a

The interface block files are supplied in pre-compiled module form.
They are accessible from 

   /itl/links/generic/lib/fl77_modules

The -I"pathname" option should then be specified on each f90 invocation
(where "pathname" is /itl/links/generic/lib/fl77_modules) to
tell the compiler where to find the modules. 

Users should review the files
