The Fortran 95 language standard is upward-compatible to both the FORTRAN 77
and Fortran 90 language standards, excluding deleted features. See What is Fortran 95? for more information.
Fortran 95 also provides an extensive set of additional language
features. For more information on these features, see What is Fortran 95?. The Fortran standard committees are responding to
questions of interpretation about aspects of Fortran. Some of these
questions may be related to language features that have been implemented in
the XL Fortran compiler. Any answers given by these committees that are
related to these language features may result in changes in future releases of
the XL Fortran compiler, even if these changes result in incompatibilities
with previous releases of the product.
