Is "storable" module the best option? storable uses a binary format which can't be edited. if you must edit the data file outside a perl program you can use Data::Dumper which puts out perl data structures. you need to be careful if you have a complex structure which loops back and such. there are options to handle that but they may make it harder to edit the data cleanly. you then read the file back and run eval on it (or use do/require). it also depends on how you write out the file itself. you may need to edit (in perl) the dumper text to make it work in your context (package space, lexicals, etc.) another alternative if your hash is simplistic is to use CSV or a DBD that handles CSV or another text format. 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/
