Explanation:
What you have settled for by using "listf @[log in to unmask]@" is the first dataset
in the database, but also any file where the filename ends with "01",
and that may/mayn't be a database file. Also; the M.P.E. file system
allows filecode representation to be alpha ("PRIV") and Numeric. When
you see "PRIV" as a filecode it simply means that the numeric value of
the filecode is negative, and again this can include non database file
types.

Ah, the memories.  Back in my early days of MPE I use to change a flat
file to a file code of -48? So when the Systems Manager did his normal
scan of files in the morning he would see this lone file with 'PRIV' and
couldn't open it!!  He would ask me what it was and how I did it but I
told him it was my way of locking a file and I wouldn't tell him how I
did it.

I would use MPEX and issue an altfile command against the file.
