ActiCalc Desktop Calculator
by Parmerlee, Inc.

  ActiCalc is an easy-to-use general-purpose desktop calculator. Its major feature is a visual calculation tape that behaves like a spreadsheet, recording all calculations and permitting prior entries to be updated. This tape has one-click integration with Microsoft Excel to allow simple calculation sequences to seamlessly evolve into complex spreadsheets. Version 2.4 introduces a small window mode that is activated with a simple toggle button. Version 2.5 enables users to cycle through any recently saved calculation tapes with one mouse click.
