To do that you might want to use: for and check on whether an item is defined
or not. Then you know the id you are on and can add or subtract depending on what you
need.
So for a starter, you could try:
for(my $MyId=0;$MyId<scalar(@MyArray);$MyId++) {
next if ( ! defined $MyArray[$MyId] );
my $MyCheckId = $MyId + 2; # looking at item two above
if ( $MyArray[$Myid] > $MyArray[$MyCheckid] ) {
# do something
}else {
# do something else
}
}
I think you see what I mean.
Wags ;)
