eighteen virtual core files that comprise the CASANOVA
package for Computer ASsisted instruction in ANalysis Of
8! VAriance. The package is coded for use on a PDP 11/40, 45 or 70
computer operating under RSTS/E, V6A-02. Those who wish to adapt
the package to other systems and/or programming languages are
9! urged to consult the BASIC-PLUS Language Manual, published by the
Digital Equipment Corporation, Maynard, Massachusetts, 01754,
as well as the Instructor's Manual for CASANOVA, provided by Lawrence.
