RPG2SQL, like IBM's WebSphere Integrator, uses a middleware PC. Unlike IBM's product, it does not participate in a native SQL environment. It is a set of function calls that could be compared to ODBC or SQL CLI (call-level interface). In other words, you connect to the middleware server with sockets, you send requests to that middleware that get relayed to the database server. The first request is a connect, then you send SQL statements that are "prepared" on that DB server, then records are retrieved. When you're done you shut down all the connections.

We usually have people running this in ILE RPG, but it can be used in COBOL just as easily. It IS an ILE thing, so good-old CLP won't work, CLLE would require the more recent pointer and integer support - we've had a project to get CLP wrappers here since I arrived but it does not have high priority at this time.

I just looked in the REXX manuals - no mention of service programs. There IS an API

Call Service Program Procedure (QZRUCLSP) API

but it depends on pointers and stuff - you might as well work in RPGLE!

It'd be interesting to have someone use this product in C - you'd have to build your declarations from our RPG-style prototypes - heh - the opposite of what most do, right? But not impossible and not even that hard. Just tedious.

Give a shout if you want a little more discussion. You can get a manual from our Wiki - http://wiki.rjssoftware.com/wiki and look in the documentation section for RPG2SQL.

Vern,

What are functions and features of RPG2SQL; the technical stuff not the
marketing?

As to REXX calling procedures in service programs...not sure... Can CL do it?
If so, REXX can.

Or if needs be I can create a C program that calls REXX to use the strengths of
each language tool.

Thanks much,

Dave
