Re^3: Dereference string in foreach

You don't need to be an utter cowdawg towards the OP -- strict and warnings are irrelevant to his issue.

I wasn't being mean, ornery or cantankerous. Take what I said at face value. If strict and warnings were turned on (as I showed) the problem would have shown itself very clearly.

> If strict and warnings were turned on (as I showed) the problem would have shown itself very clearly. Nope, it's another problem just at the same place. Using `my` fixes the errors but not the OP's problem, which is `foreach` localization and aliasing. `use warnings; use strict; my $string; my @array_of_strings=1..3; my $sref = \$string; foreach $string ( @array_of_strings ) { print $$sref; } __END__ Use of uninitialized value in print at - line 8. Use of uninitialized value in print at - line 8. Use of uninitialized value in print at - line 8. lanx@nc10-ubuntu:~$` [download] Cheers Rolf	[reply] [d/l] [select]

Anyway, sorry about that. I did not particularly mean to lash out at you -- your advice just seemed like one of those "you must use strict even for the smallest script" posts that I sometimes see.	[reply]

Oh. I seem to have missed the part where the problem showed itself very clearly. I'm still not quite sure where it is shown, actually.	[reply]
