This morning I made a change to an RPG/400 source member using LPEX and compiled it from WDSc. I ran the program from a 5250 session and the change did not appear to have taken effect, so I debugged the program. In debug mode, I noticed that the source did not include my change. I checked my compile listing and it was also missing there. I checked the source via PDM and it does not have my change and shows a last changed date of 09/01/06. I confirmed that I was working with the correct member by attempting to open it for edit in SEU. It gave me a message saying that it was locked. I closed the member in WDSc and then I was able to open it with SEU. I closed SEU and opened the member again in WDSc and it does have my change. Two questions: 1. How do I force my change to be applied? 2. How do I keep this from happening again?
