With the translation from Fortran 77 old constructs are removed, the system also reduces GOTO and statement numbers, introduces array syntax instead of explicit loops, it replaces COMMON by module, computed GOTO by CASE and checks possible execution errors, and a lot more. The new internal functions are, naturally, included, but some of them are as external functions. The system is available for Sun SPARC, HP 9000, IBM 6000, Silicon Graphics, DEC Ultrix, VAX/VMS, Convex and Cray.
The paper by John K Prentice, "Translation of Fortran 77 to Fortran 90 Using VAST-90", Fortran Journal, Vol. 5, No. 4, July/August 1993, gives a very favourable view of VAST-90 and its performance at translation. It also includes two actual examples.
