Long winded way...

Code:
my @a = ("a","b","","","c","","");
my @b;

foreach (@a) {
if ($_) { push(@b,$_); }
}

@a = @b;

Not sure if thereis a better/faster way.. but thats probably how I would do it (gotta admit, I've never had to do it before).

Cheers

There's a few ways. One pretty simple one:

@a = grep {/./} @a;

--mark
