Option: extern
-extern
Causes ftnchek to report whether any subprograms invoked by
the program are never defined. Ordinarily, if ftnchek is being run on
a complete program, each subprogram other than the intrinsic functions
should be defined somewhere. Turn off this switch if you just want to
check a subset of files which form part of a larger complete program. Subprogram
arguments will still be checked for correctness. Default = yes.
The -extern
flag is now superseded by the -usage=ext-undefined option. For the sake
of convenience, the -extern flag is retained, so that -noextern is equivalent
to -usage=no-ext-undefined option. The -extern switch may be retired eventually.
