SB> - re-create the reference to the data structure into a scalar, by SB> lifting the memory address from disk using 'Storable' (or some other SB> mechanism) huh?? that is the really garbled part. none of that makes any sense. what is 're-create'?? when you load anything into ram you never (in almost any lang or system) have control over the address it gets loaded into. the rule is well known, you don't ever write real address data to disk as that is useless upon reloading. now, as randal also asked, why do you want this? you are just learning perl and i am sure this is way above your head in many dimensions. and i am positive this is an XY problem where you want X and think Y is the solution when there is usually a much better way to do X. what is your real GOAL here and i don't mean any technical stuff. why do you want this crazy thing? uri -- Uri Guttman ------ u...@stemsystems.com -------- http://www.sysarch.com -- ----- Perl Code Review , Architecture, Development, Training, Support ------ --------- Gourmet Hot Cocoa Mix ---- http://bestfriendscocoa.com --------- -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
