Here's one way:
while(@array){
my $a = shift @array;
my $b = shift @array;
}
...I think that would do what you're asking.
>- is it possible to search an array for a certain element, and that the

>(123, 456, 156, 1354, 35164, 654656, 654, 846) should give 2
This one's easy.
for(0..$#array){
chomp $_;
if($_ == 156){
print "Found 156 at $_.\n";
last;
}
}
Take out the "last;" line if you want it to keep searching after it finds one.
