NewBie Question - array's and using the index function

Hi all,

I have a quick newbie question with my base sas code I have written that
doesn't seem to be doing its thing - what am I doing wrong.
i basically have a whole lot of query strings from search engines - each
one uses different name pairs that contain the search string that the
searcher typed in, which I want to catch and write away

e.g strings look like this
rlz=1C1GGLS_enZA291&sourceid=chrome&ie=UTF-8&q=test
and
rlz=1C1GGLS_enZA291&sourceid=chrome&ie=UTF-8&query=test33
and
rlz=1C1GGLS_enZA291&sourceid=chrome&ie=UTF-8&keyword=testingme

So here is what i have written just to evaluate if my logic works which it
doesn't seem to be... Please help


tempRefQString = lowcase(URLDecode(Referrer_Query_String));
/* Store's the URL's in a var*/

ARRAY KeyWordsPosArray (3) q query keyword;
/* Array of the various CGI name value pairs I need to look for in theURL*/
do i = 1 to 3 ;
if index(tempRefQString, KeyWordsPosArray(i)) gt 0 then do;
KN_ReferrerExternalSearchWord = 'Y';

/* If any of the array values are in the query string then mark as Y
KN_ReferrerExternalSearchWord - so that I know they are being picked up I
will do further string manipulations*/
end;
end;


Thanks in advance
Michael
