I have a lots of .txt files containing numerical data.
The following code opens a program called platon and it in turn opens a single .txt file and does various things with it.
($in_filename, $out_filename) = @ARGV;
$out_filename = $in_filename if ( !($out_filename) ); 
$ins_filename = "$in_filename.txt";          
system ("platon -c $txt_filename");

How would I change this code so it opens all my .txt files one after another (they are numbered sequentially).
cheers harry
