Re: Search element of array in another array

P.S.: A step forward: I tried IO::ALL and scalar @allwords reports 10 elements ... But still no matches found.

Perhaps you need to chomp @allwords?

Again, Data::Dumper (especially its Useqq option) or Data::Dump are useful to see the actual strings.

BTW, be careful with IO::All, it is easy to create ETOOMUCHMAGIC errors with it...

`$Data::Dumper::Useqq = 1;` This is really amazing! @allwords $VAR9 = "hat\r"; @cleanwords $VAR6 = "hat"; How can I get rid of the \r? I vaguely remember I had this problem before...	[reply] [d/l]

Probably this: `s/\r//g;` [download] (if the variable if contained in `$_`), or, otherwise, something like this: `$var =~ s/\r//g;` [download] Je suis Charlie.	[reply] [d/l] [select]
