Very roughly, if at all. It depends not only of how much memory those other processes are using, but also on the particulars of the Virtual Memory implementation of the system (if any), the amount of swap space, whether you can overcommit memory etc.
To get back to the original poster's question: the only limit on the size of a variable in Perl is memory. How much that is in practice is difficult to predict, as fglock's post indicates.

Doesn't perl represent the size as a integer or ANSI C size_t variable? Then it would be limited to 4GB or whatever based on a union of your integer size and the integer size of Larry's machine where he may have made assumptions. | [reply] |
