ftnchek  (short  for  Fortran  checker)  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 opera-
tion.
