I think that this code takes run-time argument as well. Let me know if this is the case.
What is a run-time argument of a function? Or more precises, what other arguments could a function have, if not at run-time? (The alternative would be an argument binding called Currying, but Perl does not support this).
I am nowhere able to find the routine get_opt
Neither am I. Hence, the program you posted is either incorrect or incomplete.
What is that host=s?
The technically correct answer to this would be it's a string, but I could imagine that the code you are posted is used together with Getopt::Long. This will probably answer your other questions too.
