Date of this Version
An interactive program for calculating the expected mean squares for balanced designs was developed for use on a Tektronix 4054 desktop computer (Engeman 1982). That program used BASIC string commands that did not translate well into other forms of BASIC, including that for MS-DOS machines. The program has since been rewritten to run on MS-DOS machines. Its output has also been expanded. The new version was written in BASIC on an AT&T PC 6300 and will run on most MS-DOS machines that support BASIC.
