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.

Here's a little test scenario: http://code.midrange.com/9043c56f42.html

Based on what Barbara is saying this means you can never reorder the
list of procedures. And every procedure in a *PRV list must always
correspond to a matching procedure in the *CURRENT list.
If you reorder, and you don't want to have issues, you have to recompile
everything.

Will removing the old signature always cause a signature violation for
existing programs?
