Q: How do I open numbered files like results001.txt, results002.txt, .... in an easy way?
The following example uses `internal files' to do just that:

program results
  integer :: i
  character (len=100) :: filename
  do i = 1, 5
    write ( filename, '(a,i3.3,a)' ) 'results', i, '.txt'
    open ( unit=10, file=filename )
    write ( unit=10, fmt=* ) i
    close ( unit=10 )
  end do
end program results

Q: How do I split up my project into separate files?
It is advised that a module is either put into a separate file or included in
the file of the main program. Do not put individual
subroutines/functions into separate files: 
they should always be part of a module (which can of course be a put into a
separate file).

Q: How do I manage multiple files?
A: Define in Plato3 a Fortran application project. Add all your files to the
project and let Plato3 manage (build/compile etc.) your project. If you change
a single file and rebuild the project, Plato3 only compiles the changed file
and makes a new executable. Plato3 also knows about dependencies, i.e.
if the changed file contains a module that is
being used by another file, the latter file is also recompiled. In summary:
a build step in plato3 only compiles files that have been changed/added
or depend on files that have been changed since the last build.

Q: How do I do source code and run time checking and source code debugging?
A: There are three modes in Plato3: Checkmate Win32, Debug Win32 and Release
Win32. The first mode includes extensive checking. The first two include
debugging. The last is for running a program when the bugs are removed.

Q: How do I make my program run faster?
A: Click optimise in the Optimisation list of the project configuration.
