Thanks. I have some default server already configured in .visdkrc, but relying on that is cumbersome, especially since I am trying to use different servers based on a specific user input.

After reading through some subs in VILib.pm, look like Opts::set_option('server' => $server) is all I need:

# validate options, and connect to the server

Opts::add_options(%opts);

Opts::parse();

Opts::validate();

Opts::set_option('server' => 'XXXX');

Util::connect();
