Introduction to FORTRAN 
A Reference Manual

Aleksandar Donev January 2000 Physics Department State University of Michigan Abstract:

This handout should serve you only as a reference to the commands of Fortran in the ANSI 77, 90 and 95 standards. Only rudimentary examples are given to remind you of the syntax, and some tedious details that you are not expected to remember are tabulated for reference purposes. This HTML version contains only the part on the FORTRAN 77 standard. For now, please download the PostScript or PDF files for the full text.

This material was written using the book Professional Programmer's Guide to Fortran 77 by Clive G. Page found at http://www.star.le.ac.uk/~cgp/prof77/ and several very informative and more detailed on-line Fortran courses. Great thanks to the authors of these pages for their help and e-mail correspondence. Here is a list of the web sites leading to these on-line courses. Use these links to learn more about Fortran and to find out details not present in this handout:

• A very nice introduction to Fortran 90: http://www.pcc.qub.ac.uk/tec/courses/f90/ohp/header_ohMIF_1.html
• A very detailed on-line course in scientific computing (like this seminar), with descriptions of Fortran 90, Mathematica, C and much more: http://rsc.anu.edu.au/HWS/COURSES/MATHMETH/node7.html
• A couple more informative introductions to Fortran 90: http://www.ucs.ed.ac.uk/eucs_documentation/Documents_by_Number/2669/html/notes/notes-1.html http://www.qmw.ac.uk/~cgaa260/BUILDING/INTR_F90/OUTLINE.HTM
• A more advanced introduction to modular Fortran 90/95 and to High Performance Fortran:

• And let's not forget the MSU computational physics website (in development): http://computation.pa.msu.edu/

Also, it is important to note that this HTML version of the text does not correspond very well to the actual handout due to compilation problems with latex2html. You can download and print the original text, together with the part on Fortran 90 freely as an Adobe Acrobat PDF document from: http://kepler.pa.msu.edu/~donev/FORTRAN.pdf
or as a PostScript file (opened with GhostView) from: http://kepler.pa.msu.edu/~donev/FORTRAN.ps
to the Also, you can download my C-C++ manual as well (not as fully developed):
