Running previously compiled programs

Statically linked programs that you compiled with levels of XL Fortran prior to V15.1.3 should continue to run with no change in performance or behavior. They may not run on a system with a level of the operating system different from the system on which they were compiled.

If you have dynamically linked programs compiled by XL Fortran Versions 2 through V15.1.3, you can run them on systems with the XL Fortran V15.1.3 libraries. The programs will use the current compiler data formats and I/O behavior, which are somewhat different from those of XL Fortran Version 2.
