Enforce strict

tom@margo:~> perl -Mstrict -e 'print $test';
Global symbol "$test" requires explicit package name at -e line 1.
Execution of -e aborted due to compilation errors.

Yes, thank you, you've all understood my question right. There must be something else going on ... something fishy ... something embarrassing ... `alexf@localhost ~ $ perl -Mstrict -e 'print $a' alexf@localhost ~ $` [download] Doubly embarrassing, looking back to Feb 2002, I once advised a soul facing exactly this puzzler.

Update: realized too late that you understood the reason, nevertheless may this answer stand here for others as slow as myself in understanding written english :) `perldoc perlvar` :) `$a $b Special package variables when using sort(), see "sort" in perlfunc. Because of this specialness $a and $b don't need to be declared (using local(), use vars, or our()) even when using the strict vars pragma. Don't lexicalize them with "my $a" or "my $b" if you want to be able to use them in the sort() comparison block or function.` [download] regards, tomte Hlade's Law: If you have a difficult task, give it to a lazy person -- they will find an easier way to do it.

Oh, ha! `$a` and `$b` are global variables used by sort and so are already known by perl. That's why you don't see any errors in your example. "The dead do not recognize context" -- Kai, Lexx	[reply] [d/l] [select]
