This paper focuses on ZOG, a rapid-response, menu-selection, software system intended as a general-purpose interface to a computer. ZOG databases are networks of screen-sized displays called frames. ZOGs frame and net editor ZED combines coventional text-editing facilities with facilities specialized to the network character of the database. One of the design goals for ZOG is that ZOG be relatively self-contained in terms of instruction on the use of ZOG and ZED. This paper compares two ZOG-based tools for teaching naive users to edit with ZED an on-line net users manual and an off-line users manual derived from the on-line manual. The resultss indicate that 1 off-line and on-line manual users take about the same time to complete a standard instruction sequence, but 2 off-line users use ZED more effectively at the end of the sequence.
