Hmmmm.... For me it works. Here a complete program to demonstrate the concept: `use strict; use warnings; my $var1=35; my $var2=undef; foreach my $name ('$var1','$var2') { $_=eval($name); print(defined $_ ? ("$name=[$_]") : "$name is undefined","\n"); }` [download] This prints: `$var1=[35] $var2 is undefined` [download] -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l] [select]
