Introduction to VisualWorks Smalltalk
Course Description
This five-day course provides a solid working knowledge of the Smalltalk
language and the VisualWorks Smalltalk development environment.
Participants create Smalltalk methods and classes and develop elementary
Smalltalk applications, using a broad range of VisualWorks Smalltalk
browsers and tools. Participants view and use the major subclasses
of the Collection and Magnitude hierarchies. Participants become
familiar with the built-in configuration management system and create
basic VisualWorks Smalltalk visual parts. The course format is 50%
lecture and 50% hands-on computer time.
