This submission includes 2 programs. TAPECHECK is a program designed to quickly and inexpensively test the data reliability of a magnetic tape. This is a later release of the same program submitted to an earlier DECUS tape, I think Fall 82. SETUSER is a program similiar to the unsupported utility that existed on VMS V2.0, but vanished with VMS V3.0. OCTOBER 14, 1982 JIM LELLMAN G. D. SEARLE & CO.
