Conversion to Fortran 90: a case study

ABSTRACT

The features of the new standard language Fortran 90 are introduced and discussed. In order to focus the discussion, the particular context is the conversiton of an existing published ACM Transactions on Mathematical Software algorithm from Fortran 77 to the new standard. Emphasis is on the new features of the language, including the array facilities, the use of modules, the applicability of user-defined (-derived) data types, the reduction in machine dependence of numeric codes, and the dynamic allocation of storage. The intent is that writers of software as well as those who use Fortran in scientific and engineering work will find this a helpful introduction to the new and powerful features of Fortran 90.
