sfink++ on the additional argument to split().

As for the comment, the original post did not make clear the purpose of the code block. I always code in commented paragraphs (as per Perl Best Practices), and such comments should be as specific as possible. However, I didn't want to make a big deal about that personal stylistic choice it because it wasn't germane.

Several other posters made what I think was a reasonable assumption that the purpose of the block was CGI processing, presumably based on the structure of the data and the name of the $memory_data variable. Processing of CGI query strings raises a host of issues I didn't want to get into, so I made a different assumption about the nature of the data. :)
