Hi
I know how to set optional arguments in the function definition. Is there an
intrinsic function that determines if a certain argument was actually
passed ? Like the fortran 95 present() logical intrinsic ?
My required functionality depends on whether a certain argument is specified
at all. (Setting default values is *not* good enough.).
Thanks.
