Goals 

• To learn how to write FORTRAN programs to solve scientific problems.

Introductory Lecture.  PDF Copy of PowerPoint Lecture for Fortran week 2 . 

Handouts (paper or electronic) 

• A sample medium-size FORTRAN program.
• A sample large FORTRAN program.
• A sample extremely large FORTRAN program (the WRF weather-forecast model).

Activities in Lab  

1. creating and using linux aliases.
2. add modules to share data .  
3. writing output files .
4. interpret compiler error messages . 
5. continue learning how to debug code.

• How to use emacs to create/edit FORTRAN code, enter the linux operating system, run the FORTRAN compiler, run your compiled code, and where to find, and how to view, your output.  
• How to interpret compiler error messages .

Homework Assignment.  Lab and Homework.  You will write your fortran code in stages, a little  at a time.  This is the top-down approach to programming.  To ensure that you do this, I ask that you give a different name to each version of your code.  You must get each version of the code compiled and running, before you enhance the code to create the next version.  This way, the marker can see all the versions of your code, can confirm that each version compiled and ran successfully, and can mark each one separately.

Reading Assignment  

• Skim chapters 6 & 8 of the following FORTRAN tutorials.

2. Basics: program structure, data types, programming style, conditional statements, loops, arrays .
3. Arithmetic expressions, intrinsic functions, simple input and output (I/O) .
4. Characters, strings, print .
5. Internal subroutines and functions .
6. Modules . 
7. More about arrays, dynamic allocation of arrays, key words . 
8. More about I/O . 
9. Case statement .
• Read Chapter 5 on Debugging, from  Kernighan and Pike "The Practice of Programming" (which is in the course material pack).
