FORALL: An extensible fortran system for conversationally accessing subroutine libraries

The implementation of a user‐extensible Fortran system is described. The control syntax, in which all arrays may be referenced by name, is outlined, including language‐like extensions. A summary of the algorithms implemented is tabulated. Facilities for the user to add algorithms to the system are described and the methods of handling arrays outlined. Features to facilitate portability are mentioned.
