The next revision of the standard Fortran language, commonly referred to as Fortran 8x, has now been published, at least in draft form. It is therefore possible for some of its new features to be investigated and the type of programming that can be expected when implementations appear to be explored. This paper looks at the scope provided by the proposed new features for 'semantic extension' of the language. The capability is illustrated by way of example code which could provide an extended‐precision numeric facility if implemented. The new linguistic constructs that permit this type of approach to software provision are described as they are used.
