Indeed, we have a table driven application and we want to add the capability
to the final users of this application to define their own functions by
defining the service program and procedure to call along with the parameters
definitions. This feature would be powerful in those cases when our
customers have already created functions to perform things not considered by
our application.

Well, my MAX procedure looked pretty much like yours, but the parameters
were not defined as VALUE as yours. I added this keyword a got the api
working.

How do i interpret this ? Is VALUE related to this optimization ? Wouldn't
be another way to call procedures with parameters defined as CONST or passed
by reference ?
