F77SPLIT - Split FORTRAN77 Source Files

F77SPLIT is an executable C program that reads a FORTRAN77 source code, and writes each module to a separate file. A module is considered to be a FORTRAN BLOCKDATA, FUNCTION, MODULE, PROGRAM or SUBROUTINE.

Usage:

f77split myprog.f

extracts each routine from myprog.f and creates a separate file for it.

Related Data and Programs:

EXTRACT is an executable FORTRAN90 program which extracts a subroutine, function or module by name from a FORTRAN file.

F90SPLIT is an executable FORTRAN90 program which can split a FORTRAN90 file, assigning each subroutine or function to a separate file.

FIXCON is an executable FORTRAN90 program which reads a FORTRAN file using FORTRAN77 continuation statements, and makes a copy that uses FORTRAN90 continuation instead.

HTMLINDEX is an executable C++ program which reads a C, C++, FORTRAN77, or FORTRAN90 file and writes a skeleton HTML page describing it, assuming that each subroutine includes a '!!' or 'cc' description line.

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

INDEX reads a FORTRAN program and prints every line that begins with a special index tag of '!!' or 'cc'.

Source Code:

• f77split.c, the source code;
• f77split.csh, commands to compile and load the source code;

Examples and Tests:

• f77split_prb.f, a sample file to split up;

List of Routines:

• MAIN is the main program for F77SPLIT.
• SPLIT_FILE splits up the modules contained in a single file.
• GET_NAME creates a file name based on the name of the current module.
• COMPARE compares two strings for equality.
• ENDCARD checks to see whether the current record is an END statement.
• SHORTEN_LINE removes characters beyond column 72, and trailing blanks.
