I found that using either of the tied interfaces worked as you
expect (both documented in the POD's for Perl-5.004 or later):
tie *OUT, 'IO::Scalar', \$string;
print "line 1\nline 2\n", "line 3\n";
print "The string contains:\n$string\n";
### OR this way:
$string = '';
my $SH = IO::Scalar->new_tie(\$string);
$SH->print("line 1\n"); # use the OO method
print $SH "line 2\n"; # use it like a filehandle
select $SH; # select it as default output handle
print "line 3\n";
print "The string contains:\n$string"
