F77_CLEANUP
Minor Cleanups to a FORTRAN77 File

F77_CLEANUP is a FORTRAN90 program which makes some minor cleanups to the text of a FORTRAN77 file.

In particular, in the revised program:

• TAB characters are replaced by six spaces;
• all comments begin with a lowercase "c";
• all continuation characters are "&";
• trailing blanks are trimmed;
• all (noncomment) lines are no longer than 72 characters.

Usage:

f77_cleanup input.f77 output.f77

reads the file file.f77 and creates a copy output.f77 with cleanups.

Related Data and Programs:

CATALOG, a C++ program which reads a C, C++, FORTRAN77 or FORTRAN90 program and prints every line that begins with a special index tag. If the program has been marked up expecting this convention, it is a handy way of making a table of contents of a program file.

EXTRACT, a FORTRAN90 program which extracts a subroutine, function or module by name from a FORTRAN77 or FORTRAN90 file.

F90SPLIT, a FORTRAN90 program which reads a FORTRAN90 file and creates individual files for every subroutine or function in the file.

FIXCON, a FORTRAN90 program which reads a FORTRAN77 file and changes continuation lines to use the FORTRAN90 convention.

HTMLINDEX, a C++ program which reads a C, C++, FORTRAN77 or FORTRAN90 file and writes a skeleton HTML page describing it, assuming that each routine includes a specially marked description line.

INCLUDE_FILES, a FORTRAN90 program which reads a FORTRAN90 program with INCLUDE statements, and makes a copy with the indicated files included.
