That is, if DSN=NON.TEMP.DSN is NEW and both the normal and abnormal dispositions are DELETE, then assign a special unit name. ACS routines, as best as I can see, don't have the ability to determine the disposition values. You are totally correct about VIO not being possible for a non-temporary DSN. What the OP could do in the IEFDB401, not that I'm really suggesting it, is to look at all three of the DISP parameters. If they are NEW,DELETE,DELETE, the the OP _could_ change the DSN at that point from a non-temporary DSN to an &&SOMEVAL in the SVC 99 parameter list. But now I'm getting really weird, since use of VIO is no longer as critical as it once was. > > Kees. > -- "Irrigation of the land with seawater desalinated by fusion power is ancient.
