Mitch,
There is one method that would be a short cut. GET DIAGNOSTICs can provide the total number of records in the data set after the open. That can control the number of records fetched in the FETCH INTO statement.
After the open you can code:
/exec sql
GET DIAGNOSTICS :row_count = DB2_NUMER_ROWS;
/end

I've used the following article several times as a reference:

I've never had to do a select count prior to doing the fetch.

Charles,
Would be nice if you could use SELECT INTO along with FETCH FIRST XX
ROWS...
After getting the count (select count(*) into :resultCount from...), and declaring and opening a cursor, I can successfully use
? ? exec sql
? ? fetch MyCursor for :resultCount rows
? ? ? into :ArrayDS;
? ? ? ? ? ? ? ? ? ? ? ?
But there apparently are no shorter shortcuts.
