Hello fellows, I would like to know if someone of you can tell me why SYSREVDB is using the USR4002N subprogram. The things is I noticed that the version stored on SYSREVDB is older than the version stored in SYSEXT… My best regards, ---

As you can see USR4002N returns environmental information, but it also has a “VERSION” parm field which dictates the interface, so as long as the Natural nucleus understands the version number asked for the catalog date doesn’t matter at all. ---

Thanks a lot… as I understood I may be keep the USR4002N downloaded by INPL of SYSREVDB and it does not impact anything, that’s? ---
