I browsed both Managing Catalogs, Access Method Services and Advanced Services. No effect. :-( I hope it is not licensed (and extra paid) knowledge. Regarding FM, I also use to browse/edit VSAM datasets, but VVDS is different animal. From the abend code I read I need APF authorisation, which is not available for FM under ISPF. As far as I remember, good old DITTO allowed APF mode under ISPF, but restriction was single ISPF screen (no PF9, etc.). -- Radoslaw Skorupka Lodz, Poland W dniu 24.05.2025 o 21:35, Paul Feller pisze: > You could try looking in the z/OS DFSMS Managing Catalogs (SC23-6853) manual. > From what I see there is some information about the records in the VVDS. > Unfortunately from what I can see the information does not give any detail > around offsets and lengths for the fields. > > I know I've used File Manager under ISPF to browse Vsam datasets.
