How to form a string(no spaces) from the elements of an array?

[aNewBeginning]

Suppose I wish to print 1234567890 x 3, and I wish to implement it in a reasonable way as follows:

my @count_to_ten = 0..9;
my $number_ruler = @count_to_ten x 3;
#number_ruler is "101010"
or
my $number_ruler = "@count_to_ten" x3;
#number_ruler is 0 1 2 3 4 5 6 7 8 90 1 .....

Is it possible to store a string of the variables from an array (without spaces) into a scalar?

 

[travs69]

$var = join(@array, '');

Travis had it backwards:

$var = join('',@array);

or:

$var = do{local $"; "@array";};

$" is the predefined list seperator variable.

Not sure if one way is better than another.

I prefer the former. I can see straight away that I'm joining the array with a '' separator, without having to remember what $" is...
