1. The only limitations I've encountered of 32-bit versus 64-bit is the former is restricted to 2GB of memory and (may) only support 32-bit integers.

    I cannot think of anything else that would prevent a script developed on a 64-bit build from running under a 32-bit version.

  2. Depending upon how huge the files are and how much memory you have installed, the 64-bit might allow you to work entirely in memory where the 32-bit may force you to process the file in chunks.

    Depending what you're doing with the files that may or may not be a problem.

  3. Perl works very well under windows, though there are some unix specific modules that don't compile there.
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
