Editing, compiling, linking, and running XL Fortran programs

Most Fortran program development consists of a repeating cycle of editing, compiling and linking (which is by default a single step), and running. For problems encountered during the development cycle, refer to the following sections for help.

Prerequisite information:
  1. Before you can use the compiler, all the required Linux settings (for example, certain environment variables and storage limits) must be correct for your user ID; for details, see Correct settings for environment variables.
  2. To learn more about writing and optimizing XL Fortran programs, refer to the XL Fortran Language Reference and XL Fortran Optimization and Programming Guide.
