Highly configurable Fortran program to indent and renumber statements, selectively change case of keywords or non-keywords, and do various other clean-up tasks on FORTRAN 77 source programs. TIDY can convert some FORTRAN 66 features such as Hollerith constants to FORTRAN 77. TIDY can either retain DO/END DO loops or convert them to standard FORTRAN 77 loops. It can change comment specifiers from C,c,or * to ! as in Fortran 90 (F90) style.
