The TIDY program renumbers and otherwise cleans up old and tired FORTRAN source programs. TIDY accepts ANSI Fortran 77 with a default of 19 continuation cards as well as some IBM and CDC dialect FORTRAN statements. It will also accept FORTRAN II and FORTRAN IV statements. Certain FORTRAN II statements (such as READ INPUT TAPE) are automatically translated to their FORTRAN IV equivalents. All lower case alphabetic characters in FORTRAN keywords are normally translated to upper case.

TIDY was one the first programs that was written at a government facility and subsequently widely shared among the entire Fortran community. It was originally written by Harry Murphy at Kirtland AFB. Over the years, it has moved among facilities. For a while, my group at NASA Ames Research Center maintained the program and Alice Barlow was our chief programmer. It is now cared for by Ajit Thakkar at the University of New Brunswick.

I am including this program on the CD-ROM as a convenience. The way to keep up-to-date with the latest version is to bookmark the Tidy site and download from there. The current version is maintained by

Our thanks to Prof. Thakkar for maintaining this valuable program. I am especially thankful because I have used TIDY on several of the programs in this collection.
