ftnchek (short for Fortran checker) is designed to detect certain errors
|
||
|
|
in a Fortran 77 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
|
||
|
|
77 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 77 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.
