Testing a Stored Procedure that has IN/OUT or OUT parameters via STRSQL can be daunting. For that matter, I have never been able to get this to work. What does work for me is to use IBM's iSeries Navigator's "Run an SQL script". I suspect you will have much greater luck using this approach. For example, I have a stored procedure that has 4 character IN parameters and two OUT parameters (first is character, second is an integer). The OUT parameters necessitate the use of question-marks ( quoted for characters, unquoted for integers/numbers). The following is an example of the SQL script that works (in iSeries Navigator); call LIBRARY.SPNAME ('F_NAME', 'L_NAME', 'STATUS', 'Y', '?', ?); The iSeries Navigator results are as follows:call LIBRARY.SPNAME ('F_NAME', 'L_NAME', 'STATUS', 'Y', '?', ?);Output Parameter #5 = SUCCESS00 Output Parameter #6 = 62 Statement ran successfully (1732 ms) Hope this helps!
