A radix 2 integer fast Fourier transform is organised for compatibility among small computer systems by simulating binary fraction multiplications and bit reversal as functions in basic FORTRAN. After installation the efficiency can be improved by machine code replacement of some parts.

Many parallel extensions to FORTRAN have been proposed by 'supercomputer' manufacturers. The major differences between these language extensions is reviewed briefly. The Principle of Conservation of Parallelism is also introduced, which is argued to be a desirable foundation on which to base the dev
