Hmm, the marketing material I have here (for the XSIS product, V2.1 and 
3.0) seems to suggest a broad spectrum, along the lines of "integrated 
application suite."  Outliner, Business Charts, Forms, Databases, Maps, 
Spreadsheets, DTP, etc.  An Expert System Shell (HUMBLE) thrown in for good 
measure.  Management of security and access levels.  Must have made The 
Customer quite happy.

BTW, the spreadsheet component ASP, the "Analytic Spreadsheet Package", has 
been described by Kurt Piersol in the OOPSLA 1986 proceedings, pp. 385--390.

HTH,
