An application development environment for Smalltalk for Windows, Mac and Unix from Cincom Systems. Introduced in 1991, it includes development tools such as a compiler, debugger, GUI builder and class browser. Cincom acquired the VisualWorks product line from ObjectShare, Inc. in 1999 and packaged it with the ObjectStudio toolset to make up its Smalltalk development environment. VisualWorks was originally ObjectWorks from ParcPlace, which was spun off of Xerox PARC in 1987 and merged with Digitalk in 1995 to form ObjectShare. See
