Larry- I think what you are trying to do can be accomplished with one statement:

SELECT count(*), distinct *;
FROM masterfile;
INTO CURSOR countfile;
WHERE inactive <> "Y";
GROUP BY agegrp, district

This doesn't directly apply to your question, but could possibly reduce the time it takes to create your countfile table.
