Hi Peter:
Michael Metcalf's (formerly of CERN) tutorials at
http://wwwinfo.cern.ch/asdoc/f90.html might be a good place. Others are
http://www.scd.ucar.edu/tcg/consweb/Fortran90/F90Tutorial/tutorial.html
http://www.cs.mtu.edu/~shene/COURSES/cs201/NOTES/fortran.html and
http://www.obliquity.com/computer/fortran/
Just be careful if you inherit someone else's code. They can be
difficult to comprehend even with comments. If you are starting a new
project, carefully review whether fortran is the most appropriate
language. Not trying to start a language war here, just save some
headache.
I found that the combination of Perl on the front end (option/file
parsing), and fortran on the backend works quite well. Sometimes you
dont have that option, but it is nice if it is available.
