z/VM 5.2 and the S disk

[Steve Gentry]

Hello.  I am installing 5.2 and need to add a couple of EXEC's to the S disk (mdisk MAINT 190)   I've accessed  190
as another mode, added my two execs and rebuilt the CMS saved segment.  Logged off of the user, logged
back on.  When I do a  FILELIST  on the S drive, the EXEC's don't show up, but when I access 190 in another mode
they are there.  Therefore, I don't think they are being executed.  What do I need to do to get these EXEC's
to show up on the S drive?
Thanks,
Steve G.
