create cursor temp1 (key1 c(fsize('key1','result')), key2 <type> <size> )Alternatively, if this is based on an existing table, you can use SQL to create the cursor for you:
SELECT key1, key2 FROM result WHERE 0 = 1 INTO CURSOR temp1 READWRITE NOFILTERThe trick here is to use a WHERE clause that will return no records - so all you get back is an empty structre.
