Re: If/else within a foreach loop to check strings within an array

[choroba]

Very similar to a recent question. See Re: Trying to compare a string....

Update: In your case, regular expression would be the easiest solution:

my $dna = shift; # Get the first command line argument.
if ($dna =~ /[^ACTG]/g) {
    die "Non-nucleotide at " . pos($dna);
}
