While your implementation is a little inefficient, I don't see any problems with it. Because you are using the diamond operator
(<>) to read data, that means you're running it from the command line with something like
# perl -w foo.pl <DataFile.txt
Is that right? Because if you're just using
Then I'm not surprised that it appears to be hanging -- it's actually waiting for data to arrive on STDIN so it can start to parse.
