Chapter 14: Migrating Fortran Code

Introduction

This chapter examines the process of migrating Fortran code to the Microsoft Windows operating system. This migration may be to either the Win32 subsystem or the Interix subsystem.

Fortran is relatively easy to port between platforms, largely due to the high degree of standardization between Fortran compilers and to the types of applications for which Fortran is typically used.

The main difficulties with migrating Fortran code are often associated with eitheran application s integration with other languages or its use of third-party libraries.

This chapter covers how you should:

• Gather and analyze data regarding your Fortran application.

• Plan the migration of your Fortran application.
