Latest Version: 3.3

ftnchek is a static analyzer for Fortran 77 programs. It is designed to detect certain errors in a Fortran program that a compiler usually does not. ftnchek is not primarily intended to detect syntax errors. Its purpose is to assist the user in finding semantic errors. Semantic errors are legal in the Fortran language but are wasteful or may cause incorrect operation. For example, variables which are never used may indicate some omission in the program; uninitialized variables contain garbage which may cause incorrect results to be calculated; and variables which are not declared may not have the intended type. ftnchek is intended to assist users in the debugging of their Fortran program. It is not intended to catch all syntax errors. This is the function of the compiler. Prior to using ftnchek, the user should verify that the program compiles correctly.

Call for volunteers

Would you like a chance for GLORY, FAME, and the undying gratitude of countless Fortran programmers? Now is your chance! If you would like to contribute to bringing ftnchek up to the Fortran 90 standard, click here for more information. If you have trouble connecting to the ftp site, or find the downloading too slow, try netlib or sunsite. If you are not in the United States, you may prefer to use one of the netlib mirror sites or one of the sunsite mirror sites.

NEW: ftnchek is now a SourceForge.net Logo project

This move happened only recently, and so the SourceForge project site for ftnchek is still under development. You should still come to this location for downloads of the distribution source code or binary executables. For those who would like to assist in the development of ftnchek, the most recent source code (still experimental) can be checked out from the CVS repository at SourceForge.
