Back in the mid 1980's I used software by Javelin software that could be used to serve the same purpose as a spreadsheet. Javelin was different in that one wrote rules based on variables not cells. It was much easier to avoid the errors that so often lurk hidden beneath the visible cells of a spreadsheet.

Unfortunately, I never met another user of the software and the company eventually went nowhere. The spreadsheet was a concept very easy for bookkeepers, accountants and other non-programmers to understand. Not so much with (the better) Javelin.

Here is an add for the software from 1985: http://www.thecomputerarchive.com/archive/Software/Applicati...

The closest modern equivalent to Javelin is Quantrix Modeler, although it doesn't seem to have the breadth of functionality that Javelin did.
