PD:Z4.NOT The file Z4.TXT in PD: is a copy of some of the transparencies from my presentation on ZCPR4 at the Trenton Computer Festival. Parts of the presentation, particularly those on Ada and my current computing environment (which includes a SUN 3/260 with 8M bytes of RAM, 237M bytes of disk, running 4.3 BSD UNIX with SYSTEM V extensions with SUNTOOLS), are not included in Z4.TXT.
