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
|
|
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.
