Fwd: Execute Failed with Stored Procedure Call

I've cross posted this since it's an RPG/stored procedure question.

Thanks!

Hi folks -

Could someone help me out with this? I'm trying to call a stored procedure
from my PHP script. Lots of help from lots of folks, and it's very much
appreciated. I've decided to use the MODS approach. I'm getting an error on
the db2_execute...here's a link to the PHP code:
http://code.midrange.com/09a32d9a0e.html

I know the connection is being made, and I know the db2_prepare is
successful. I'm passing two parameters to the procedure and expecting an
array (MODS) back. Do I need to specify the array in the db2_prepare
statement?

Here's my CREATE PROCEDURE statement that I executed from STRSQL:

CREATE PROCEDURE INVENTORY/SPR101R(IN pInVnda CHAR ( 5), IN pInMdl
CHAR ( 20)) LANGUAGE RPGLE NOT DETERMINISTIC READS SQL DATA CALLED
ON NULL INPUT EXTERNAL NAME 'NEWSYS/SPR101R' PARAMETER STYLE GENERAL

Here's the salient part of my RPG code:

Exec SQL
Set Result Sets For Return To Client
Array :ReturnDS For :WkRowcount Rows;

This works when I call the procedure from iSeries Navigator.

Thanks!
