The traditional approach is to just use the filehandle twice:

sub openOut {
    select *main::OUT = *main::OUT; # squelch "used once" warning
    ...

Alternatively, you can disable the warning, see warnings:

sub openOut {
    {
        no warnings 'once';
        select *main::OUT;
    }
    ...

The best approach IMO would be to do away with the global filehandle names alltogether and pass in the filehandle from the main program. but I guess that's beyond the scope of your question :)
