sarani:

You didn't show enough code & data to be able to say for sure. But one thing occurs to me: Perhaps you've got blank lines in @plines, so you're asking for characters after the end? Try inserting the following line as the first line in your inner loop to check:

print '"',$pline,'": len=',length($pline),"\n";
