CLEAN77
Clean up a FORTRAN77 File

CLEAN77 is a FORTRAN77 program which can apply simple conventions about indentation, statement numbering, and so on, to improve the appearance of the text of a FORTRAN77 file, by Gregory Flint.

CLEAN77 can

• force DO loops to end with a CONTINUE statement,
• renumber labeled statements, with a user chosen increment,
• move FORMAT statements to the end of a module,
• resequence statement numbers,
• convert Hollerith fields to quoted strings,
• convert between "long" FORTRAN and 72 column FORTRAN lines,
• replace INTEGER*2 by INTEGER, REAL*8 by REAL, and so on,
• indent the contents of DO loops, IF-THEN-ELSE and WHILE blocks.

Warning: CLEAN77 will not handle TAB's correctly. It will think they are COMMENT lines, and it will place a "C" in column 1!

Languages:

CLEAN77 is available in a FORTRAN77 version.

Source Code:

• clean77.f, the source code.
• clean77.sh, commands to compile the source code.

Examples and Tests:

FILE1 is an example file to be input to the program.

• file1.f, the original file.
• file1_new.f, the cleaned up file.
• file1_output.txt, the output file.

FILE2 is an example file to be input to the program.

• file2.f, the original file.
• file2_new.f, the cleaned up file.
• file2_output.txt, the output file.

FILE3 is an example file to be input to the program.

• file3.f, the original file.
• file3_new.f, the cleaned up file.
• file3_output.txt, the output file.

FILE4 is an example file to be input to the program.

• file4.f, the original file.
• file4_new.f, the cleaned up file.
• file4_output.txt, the output file.
