Abykus SE (Standard Edition) is a FREE spreadsheet program designed for business and scientific applications. The program combines object-oriented functionality with traditional spreadsheet operations, allowing you to store multi-value data types (such as arrays and matrixes) in a single cell.
Abykus has also replaced the standard "A1" cell naming convention with a significantly more powerful notation that uses numbers (i.e. algebraic expressions) or even other cell addresses to represent a cell´s row and column position. This powerful, yet intuitive, new convention makes it possible to create dynamic cell addresses that reference different cells depending on the results of a specific calculation.

Functions can also tailored to your specific needs, using an integrated script language (which uses a syntax that´s similar to the C programming language). Scripts look and behave like built-in functions and are easy to maintain and share between worksheets, since they are created, stored, and accessed from external library files as opposed to being imbedded in the worksheet itself.
