The right conclusion for the wrong reasons Wolf! The spaces are the result of
interpolating the array into a string, and the presence of a newline on each
array element is immaterial:
my @arr = ('A', 'B', 'C', 'D');
print "@arr\n";
print @arr, "\n";
**OUTPUT
A B C D
ABCD
In general, it's a bad idea to put variables inside double quotes unless know
what it means.
my $var = $value
is much more likely to be right than
my $var = "$value"
and the latter is very similar to adding zero to a numeric varibale.
Cheers,
Rob
