The program (porabably) reads data from STDIN (standard input).
Windows and Unix allow you to "pipe" a textfile to STDIN so that when
the program tries to read from STDIN, it will get the contents of the
file.
Usage: say I got a program called program.pl and an input file called
input.txt, both in the same directory. To pipe, execute the program as
follows:
program.pl < input.txt

You may simply be able to run the program with its input fed via a
pipe.

open(my $process, '-|', 'myprogram', 'and','its','arguments') or die
$!;
print $process "$_\n" for @the_input;

I you need more than this then I "Expect" (hint,hint) there's
something on CPAN to help.
