Towards FORTRAN VI?
M. J. R. Healy · The Computer Journal · 1968
Examination of a number of FORTRAN compilers compatible with the ASA standard shows that they have many extra features, and that several of these are common to many compilers. It is suggested on these grounds that a ‘super-standard’ FORTRAN, standing to ASA FORTRAN as this does to ASA Basic FORTRAN, might be defined.
