The files CoMoChaT.dvi and CoMoChaT.ps contain a DVI and PostScript version, respectively, of the book Computational Modular Character Theory by G. Hiss, C. Jansen, K. Lux, and R. Parker. This book describes the main computational methods to deal with modular characters. It is the theoretical background of the MOC system of the same authors.
This book was completed on July 27, 1992. Displayed is a slightly corrected version of November 11, 1993, containing some additional references.
