This document, which is part of the XL Fortran documentation suite, describes the syntax, semantics, and IBM(R) implementation of the Fortran programming language on the Linux(R) operating system. Although XL Fortran implementations conform to Fortran 95, parts of Fortran 2003, and other specifications maintained by the ISO standards for the Fortran programming language, they also incorporate many extensions to the core language. These extensions have been implemented with the aims of enhancing usability in specific operating environments, assuring compatibility with other compilers, and supporting new hardware capabilities.
