in reply to Writing to command line when prompted

I am not sure I completety understand what you are trying to do, but giving filenames on the commandline is quite easy. You could simply do: 
my ($filename_in, $filename_out) = @ARGV;

which gives you the two filenames in $filename_in and $filename_out.

    Though I am sure that the better approach is to change the first script, here is a (very) simple solution to feed the two filenames to the script.

    I assume your first script looks something like this: 
    use strict;

my ($filename_in, $filename_out);

while ($filename_in eq "") {
  print "IN file: ";
  $filename_in = <>;
  chomp $filename_in;
}

while ($filename_out eq "") {
  print "OUT file: ";
  $filename_out = <>;
  chomp $filename_out;
}

print "IN:  [$filename_in]\n";
print "OUT: [$filename_out]\n";

    Then you could use this script to execute the first script and feed the two filenames to it: 
    use strict;

my $command = "./script1.pl";
my ($filename_in, $filename_out) = qw(infile outfile);
system ("echo \"$filename_in\n$filename_out\n\" | $command");

    Assuming, of course, you are on a Un*x machine, echo is in your path,the first script is called "script1.pl", etc.
