in thread Return the contents of a file

I REALLY do like this one. I've found that it works great for small files. Has anyone had any experiences using this technique w/ something large like a *.cvs file from a database dump? Are there any memory issues to handling a variable that large. -- I shouldn't thinks so. Hmmm...

    There *are* memory issues in having very large variables, just as there would be, presumably, in any language. Perl variables take up a lot of space. From perlfaq3: 
        When it comes to time-space tradeoffs, Perl nearly
    always prefers to throw memory at a problem. Scalars
    in Perl use more memory than strings in C, arrays
    take more that, and hashes use even more.

    I mean, if you *can* process a file line by line, it's best to do so.
