    And obviously if you wanted cmd line arguments just add them to the exe line below. 
    
$pid = open(PROG, "| /path/to/program -a v1 -b v2 ");
print PROG "input to program\n";
close(PROG);

    See IPC::Open2 and IPC::Open3 for reading from STDOUT, STDERR, and writing to STDIN all for the same application.
