Lotus Improvとは 意味・読み方・使い方

Lotus Improv was a spreadsheet program from Lotus Development that attempted to re-define the way a spreadsheet should work. Instead of treating the grid as the system for referencing data, Improv made all data exist in named ranges. Operations on the data then referred to these names, rather than the cells. Adding two columns of numbers in traditional spreadsheet might say =A1+B1 and then copy that into the cells in a new column, whereas in Improv the formula would be something like income = widgets + tax. Improv formulas are designed to be more resistant to change in layout of the sheet, and retain semantic content that traditional spreadsheets ignore.
