Splitting a string with placeholders

[Bryan]

I have a string like this:
my $string = "A\tB\tC\t\t\t\t\t\t\n";

When I do:
my @array = split("\t", $string);

I get the following array:
@array = ["A", "B", "C"];

The placeholding '\t's are lost.

How can I keep these so that my array is like this:
@array = ["A", "B", "C", "", "", "", "", ""];

Thanks,
B

Did you check the documentation of split()?
<quote>
split /PATTERN/,EXPR,LIMIT
[...] If LIMIT is
unspecified or zero, trailing null fields are stripped [...]
If LIMIT is
negative, it is treated as if an arbitrarily large LIMIT had
been specified.

If I'm not mistaken, there's no 'trailing null field' here,
because it's an un-chomped string ...

Thanks John,

I need to omit the placeholder for the \n however. How do I do that?

BTW, where did you find the -1 thing? Its not in the perldoc -f split
info...

Cheers,

Chomp $string before you split it.
