So what is the best practical "how to" answer for the OP? bulk88 has already given that answer in How to access the contents of a specific memory address?. The long and short of which is that: it is possible to obtain access to raw address values of the PV component of Perl scalars using pack 'p' & 'P'; but there is not much that you can usefully do with them once obtained. Any attempt to manipulate pointers obtained that way -- beyond reading the contents of the memory the point at -- will simply segfault. 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?	[reply]
