I am working on AIX platform using DB2 version 7.2

I have an application running on oracle which calls stored procedures with the following syntax:

"{CALL Hello (?, ?, ?, NULL, ?, ?, ?, %l, %l, %l)}"

This works pefectly with oracle athough gives the following error msg in DB2 :

"[DataDirect][ODBC DB2 Wire Protocol driver][DB2]range for host variable .
X396 Literals are not supported as sto"

As I found from sources on the web, DB2 call of stored procedures does not support literals but would appreciate if any one can provide more information.
