-404 on OPEN cursor

This is either something really stupid on my part, or a real problem. I prepare a select statement (SQLCODE == 0) after the prepare I Declare a cursor for the prepared statement (SQLCODE == 0) after the declare I OPEN the cursor I just declared SQLCODE == -404 (Cursor not available) I triple checked that the cursor name I tried to open was the same as the one I declared, and did the same for the statement I prepared and declared the cursor from. Any ideas will be most appreciated, (The cursor appears in an ESQL/C module which is compiled along with a 4GL module into an executable - the cursor is in the E/C because that's where the variables I intend to use exist; I wrote a short EC program to verify that I was preparing, declaring and opening properly; HP-UX 10; Informix 7.21)
