The best advice I can give is : 1) perldoc perlvar 2) go out and buy the perl pocket reference from oreilly, it's good. btw $~ is a rarely used variable for Perl formats ( part of Perl's reporting past, that people rarely use these days) it's more than likely to be someone refusing to declare a variable when there is one free to bend to their use. However that said, they might be using formats; look for lines like: 1) write ..... 2) format somename= .... I like formats, but I'm in a minority ;) -- Frank Booth - Consultant Parasol Solutions Limited.
