in reply to why does this perl routine error?

The 1st "Use of uninitialized value in split" warning message you get is because the @url array does not have more that one element. Therefore, $url[1] is undefined. You can prove this to yourself by adding this debug line:

@url = split( /Realtime koers $aandeel/, $html ); print scalar(@url), "\n"; # show number of elements in array
