in thread Is it possible to write to STDIN ?

Hey, this one is interesting and seem very likely what I am looking for... but please have a look for what I am planning to do, and could you advise can I do this inside the code rather than pipe it from the shell?
$ENV{REQUEST_METHOD} = "POST"; open F, "testplan.txt" or die $!; while ( chomp ( my $data = <F> ) ) { ### DO ANYTHING TO MAKE $data BECOME STDIN ### # the main() script that reads and handle the form # print final result # next test plan data } close F;

    You could close STDIN and re-open it as a normal filehandle:
    close(STDIN); open(STDIN, 'foo'); print $_ foreach(<STDIN>);
    The documentation for 'open' shows how to save and restore filehandles, and some other dirty tricks you can play.
