This system offers translation
in both directions, from Fortran 90
to Fortran 77 and from Fortran 77 to Fortran 90. 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.
