From the author of the original 1992 game "KYE", the TreeCel calculator was inspired by the shortcomings of the common spreadsheet programs. The TreeCel calculator tries to improve things by: 1. Showing an expression and its results side by side 2. Using simple and clear constructs like IF and FOR. 3. Allowing structured data like arrays. 4. Using a tree-like structure. 5. Step by step debugging.
