Well, it your expectation is a complete running program, then this will have to wait a while until I finish up some other things (many of which happen to be different sample programs). If all you want is answers to some of these questions, then I probably give you a reply with the code snippets involved later this evening. Rick On Mon, Mar 9, 2009 at 12:38 PM, Rony G.

A package is self-contained and completely defined by the table within the package. There's no way to dynamically change those tables, so the best solution for that level of control is to use a different dll stub for ones you don't wish to have loaded for an environment. The loader entry you refer to is just an initialization routine that Rexx will call when your package is loaded. It doesn't control the registration of any of the package entries.
