That's right. But let me add my 5cents to it. If you decide to use the
construct "while ( <MYFILE> )..." then it better be
while( defined(<MYFILE>) ) {
//...
}

The code given you has an error. You read the line into $line, but the
regex is being tested on $_. Either do:
while (<MYFILE>) {
next if /^\s*$/;
# ...
}
or
while (my $line = <MYFILE>) {
next if $line =~ /^\s*$/;
# ...
}
