About 40 years ago — "An advanced object-oriented spreadsheet package for the Smalltalk-80 system Asp™ is an analytic spreadsheet package that provides access to the full power of the Smalltalk-80™ programming environment. Developed by Xerox Special Information Systems (XSIS) as part of The Analyst™ Workstation System, ASP is now available as a separate package for the Smalltalk-80 environment. Unlike other spreadsheet packages, ASP is designed for the analysis of more than just numbers and labels. Vectors, points, collections of data, text, charts, files, and images are just a few types of objects that ASP can manipulate and display. While ASP provides a large array of predefined functions, it is also extensible. By adding new methods to the Smalltalk-80 environment, ASP can be instantly expanded to match user needs, without requiring extensive knowledge of either ASP or the Smalltalk-80 system." http://www.bitsavers.org/pdf/xerox/xsis/XSIS_Smalltalk_Products_Apr87.pdf http://www.bitsavers.org/pdf/xerox/xsis/XSIS_Smalltalk_Produ...
