Hi all Sorry for this question, I believe it is too trivial to many of you. But I just can't understand it (after hours and hours of reading ILE manuals). I guess I'm just stupid. I had a program and a service program. Now, I deleted the service program. Why is the program still running? I thought it is because the service procedures are statically binded (or copied?) to the program. But then, why by updating the service I make the changes to the program without recompiling it? If my program can run without the service, do I have to distribute the service program when I send it to the client? Thanks in advance. Boris.
