As other had said - not a good idea, better to pass the filename or maybe record by record through a pipe?

On the memory issue, adding RAM may not help if you are only on a 32-bit machine or OS. The largest address on 32-bit is (2**32)-1, which gives a process address space of 4GB. Of this the kernel reserves a sizeable chunk - up to half (2GB) on some operating systems. Then you have the run-time libraries, perl itself, etc. using up address space. A 64-bit machine (in theory) has a limit of 16-Exobytes.

Then some operating systems (Windows) pre-allocate the heap-size at compilation time, which by default is only 1MB on Visual Studio. There are ugly hacks around this limit, but I doubt perl employs them.

Back to the drawing board I think.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
