When a program is compiled it will always reference the "Current" group

the Exported signatures.

Chris, that won't work. There's only one ordering for the procedures in a service program. The older signature doesn't keep its own ordering.

If you must change the order, then you must also ensure that old programs will _not_ continue to function, but instead get a signature violation, since they would be calling the wrong procedure.
