From the OP, IPC::Run3::run3 does not seem to work, I have included a working example below. (ActivePerl 5.10.1, IPC::Run 0.043) This will run the program in batch mode, which may or not work, or be what you want in your case.
use strict;
use warnings;
use IPC::Run3;
my (@fromme, @tome);
## Setup my input...
push @fromme, "3*12\n";
push @fromme, "40*4\n";
## Do it; running CLI calculator, but could be anything
unless (run3( "bc.exe", \@fromme, \@tome, \@tome )) {
## STDIN STDOUT STDERR ...for the program
print "ERROR in command\n";
}
print "Return code = $?\n";
## Return output
while ($_ = shift @tome) {
print "$_";
}
__END__
~~Output~~
Return code = 0

Maybe update your post with more detail of what you wish to do.
Good luck. -c

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
