一般的FOrtran程序编译器只能检查一般的错误，而这个软件可以起到一般编译器不能起到的错误检查、程序优化作用。-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 written in C.　To build ftnchek, you must have a C compiler

for the machine on which you wish to build it.　The URL for ftnchek s

home page is http://www.dsm.fordham.edu/~ftnchek.　Source code, binary

executables for some platforms, and other information are available

there.
