_cmd.Parameters[name].Direction = direction;

2) I refuse to use the ODBC driver for the AS/400, it has caused me nothing but grief every time I’ve tried it. If you have that driver, you should also have the OLE/DB driver, and if I have to pick between the two I would recommend OLE/DB.

3) You are using CALL on the CommandText property and trying to send the parameter there -
cmd.CommandText = “CALL CMSFIL.SPCONCUR(’0′)”;

When I do SPROCs against the 400, I ONLY specify the qualified procedure name:
cmd.CommandText = “CMSFIL.SPCONCUR”;

The provider should do the rest of the work.

I hope this helps.

I am using a ODBC connection for executing the storedprocedure on as400.

I am getting the error,

connected to the datasource

Here is part of my code,

conn = new OdbcConnection(constr);
conn.Open();
System.Threading.Thread.Sleep(20000);
Console.WriteLine(“connected to the datasource”);
OdbcCommand cmd = new OdbcCommand();
cmd.CommandText = “CALL CMSFIL.SPCONCUR(’0′)”;
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection = conn;

cmd.Parameters.Add(“@RSLT”, OdbcType.Char, 1).Direction = ParameterDirection.InputOutput;
cmd.Parameters["@RSLT"].Value = “0″;
