Hello, I have the following in a hash table named [info] Hash Table Name: info Item: Buggs2008 Data: 5f67d56b2beb4a8b8ff3433eea054532,2008/11/19 @ 11:20 pm Let's say I am looking for his gatekeeper, "5f67d56b2beb4a8b8ff3433eea054532" , how can I search the hash table based on on that and either get it to return a 1 or $true for found. Here's what I have so far but its not working.
test {
;5f67d56b2beb4a8b8ff3433eea054532
var %search = 5f67d56b2beb4a8b8ff3433eea054532
echo -a $hfind(info,$+(*,$gettok(%search,2,44),*),0,w)
}
Thanks in advance, Cheers, Jay

If the data is always in the same format, and assuming there is only ever 1 match for your search criteria, you can use this:
test {
var %search = 5f67d56b2beb4a8b8ff3433eea054532,*
echo -a Number of matches: $hfind(info,%search,w,0).data
echo -a Data from match: $hget(info,$hfind(info,%search,w,1).data)
}

When I design a hash table I like to make the identifying piece of data that I am most commonly going to be searching for the item name. So you would search for ... $hget(info,<gatekeeper>) What are you searching for most often in the hash table? Nickname? Gatekeeper? To answer your issue, you need to use the .data property when searching the data field. Without it, $hfind is looking for a match in the item's.
$hfind(name/N, text, N, M)
Searches table for the Nth item name which matches text. Returns item name.
Properties: data
If you specify the .data property, searches for a matching data value.
If Genius' code doesn't work it is because you specify the Nth item name BEFORE the w signifying wildcard search. Try... test {
var %search = 5f67d56b2beb4a8b8ff3433eea054532,*
echo -a Number of matches: $hfind(info,%search,0,w).data
echo -a Data from match: $hget(info,$hfind(info,%search,1,w).data)
}
