Thanks for your reply,

Sorry I wasn't clear about where the lines were missing. They are missing at the end of the file, not randomly throughout.

I have narrowed the problem down to the handleSeps sub, which is the lion's share of the program. I will have more time today to dig into it a little more and pinpoint the exact problem.

I have turned buffering off with no change in behavior, and it looks like my program never exits the loop, because the file never closes, and my program hangs at the console. This is even more perplexing, because if I just use an explicit filehandle (ie $myfile = $ARGV[0]; open IN ">$myfile";) everything works as expected.

Thanks again,
digger
