Summary:

The Smalltalk-80 system is an integrated, graphical, and interactive programming environment with capabilities for producing highly functional contact with personal computer systems. This book, a revision of Smalltalk-80: The Language and its Implementation, includes the latest developments and newest features of Smalltalk-80 Version 2.

The book is intended for programmers or programming language designers interested in the Smalltalk-80 language and its development environment on a particular kind of hardware system. It assumes that the reader is familiar with at least one programming language and with sequencing of instruction in a computer.
