Redirecting a print statement to a scalar variable

Asked by paulca in Perl Programming Language

Tags: redirect, variable

I have a subroutine that performs a print statement as its last command as in the following:

sub test {
     # ...

     print "how can I capture this in a variable?\n";
}

I am not allowed to change the subroutine.  Is there a way to capture the information in the print statement into a variable when I call the test subroutine?
