Got this one on Perlmonks: http://www.perlmonks.org/index.pl?node_id=111088 Also, there's been a fair amount of recent correspondence on the subject of global variables on the same forum. But then you should know that, davorg ;-). Also, a quick Google on "global variables" gives lots of pages, illustrating that they are bad in many languages, including Visual Basic. Any guide to "use strict and warnings" should also include a note about modperl, in that both global variables and uninitialised values cause modperl to break. Go ahead and write one. Nice one Dave. davorg++ Ivor. BTW 'tachyon' should be coming to the emergency social tonight @ Penderel's Oak.
