To see the sucker in work try:
//echo $gettok(.........WHY?....., 1, $asc(.))
It will return WHY?
Don't get me wrong, but why? is hardly the first token. I doubt there will me much resistance on this point. But, I often delinate data I store with ; or . or some other character I know I won't use in the data itself. The problem is sometimes the data is empty, and in these cases I have to put a zero and code that a zero means null or the bugger gives me the next items which really isn't right...
