Need Help??

in reply to check if an element exists in array

If the Hash of Arrays is too high tech for you, you could also simply concatenate the numbers in a comma seperated string, so that Jims entry would be "12,57".

The if statement in mscharrers code would then look like:

if (!exists $people{$name}) {
    $people{$name} = $value; # store array with one value
}
else {
    $people{$name} .= ",$value"; # push 2nd,3rd,.. value on array

You can just print the string stored in the hash or get at the numbers with my @numbers= split /,/,$value
