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The -extern flag is now superseded by the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.
