The 'system' function call is not a part of Fortran, but some 
fortran compilers links with the C library, where 'system' is found.

The 'system' call is neither a part of Ada, and you must either
import the 'sysyem' call, and link with the C library, or use
a (vendor-supplied) library. In gnat the package 'gnat.os_lib'
have a function spawn doing this, and that is easier to use than
an imported C function.

Starting gnuplot can be done this way, but limits comunication 
between the the Ada and gnuplot process to the command line of
gnuplot. If the problem require more comunication, a different 
approch must be used.
