Stored Procedures on SE Runtime

Aaargh! Has anyone shared this experience? We are authorized Informix developer-resellers using Standard Engine 5.01 on AIX. We recently took advantage of the fact that Informix offers a lower cost "runtime" version of the engine to deliver a client-server system to a customer on a tight budget. Originally, no stored procedures were part of this system. Recently, we tried to improve the partitioning and performance of this system by adding a stored procedure. We developed and tested it on our Informix installation, a full development version of SE, at the same release number as the customer's runtime. But when we went to create the stored procedure on the customer's system, the runtime choked on the DDL. We thought that perhaps the runtime would not allow _creation_ of the stored procedure, so we used the full product to create the stored procedure in the database, then went back into dbaccess under the runtime to issue an EXECUTE PROCEDURE. It promptly died, saying "Cannot read system catalog (sysprocedures)." A call to Informix technical support yielding the following. Me: "I'm having a problem with the runtime product." Informix: "I need a serial number." Me: "I'm onsite at a customer location. That will take a while." Informix: "Well, I've got to have it before I can talk to you." Me: "OK ... [run myself ragged for a while] ... here it is ..." Informix: "Runtime is an unsupported product." Me: "What?!" Informix: "We don't provide support for runtime at all. You can't buy it, we don't have it." Me: "Then why the heck did I have to get a serial number??!! Can't you at least tell me whether stored procedures are supposed to work with runtime?" Informix: "No, we don't know anything about runtime. It's not in our database." We are now trying to work through Informix Sales channels to figure out why the !@#$% they are peddling a product that they disavow completely and entirely. It seems now that not even Sales seems able to define for me just what the runtime product is, and how it might differ from the full product.
