arrays

[skottieb]

hello,
I am passing a scalar to a subroutine so it goes in as $_[0], lets say the scalar is a 5 digit number (12345), how do i split the scalar into a list, ie: $_[0] = 1, $_[1] = 2, $_[2] = 3, ect, ect..

ive been shown the code once before but i cant remembet it.

please help

IF you used to do this:

&subroutine($scalar);

You can instead, do this:

&subroutine( split(//, $scalar) );

That would pass the sub the list. Or you could to the split after you passed it in:

sub subroutine {
my @numbers = split(//, shift);
# ... do yo thang!
}

Hope that helps.
