Package ftnchek

Static analyzer for Fortran 77 programs

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.
