The Language Reference is part of a documentation suite that offers information on installing and using the XL Fortran compiler on Linux(R). In addition to the Language Reference, this suite also includes:
Fortran (FORmula TRANslation) is a high-level programming language primarily useful for engineering, mathematical, and scientific applications involving numeric computations. This document is a source for users who already have experience programming applications in Fortran. Users new to Fortran can still use this document to find information on the language and features unique to XL Fortran, though this reference is not a programming tutorial.
This document defines the syntax, semantics, and restrictions you must follow to write valid XL Fortran programs. The compiler detects most non-conformities to the XL Fortran language rules, but may not detect some syntactic and semantic combinations. The compiler can not detect all combinations for performance reasons, or because the nonconformance is only detectable at run time. XL Fortran programs that contain these undiagnosed combinations are not valid, whether or not the programs run as expected.
