Abykus 3.0 is spreadsheet software designed to run on Windows Operating Systems. The interface is simple and intuitive, making it easy to learn and a great choice for an individual, educator or small business owner looking for a single, inexpensive program that can handle a wide range of applications. It requires less than 3 megabytes of disk space and does not create or access files outside the folder used to install it. Despite its compact size, the spreadsheet incorporates more than 190 built-in functions, an integrated script language, and a powerful statistics wizard. Up to 32 separate worksheets can be loaded at one time, each expandable to 65534 rows and 255 columns. For the more advanced user, Abykus offers capabilities not found in other spreadsheets. For example, you can store up to 8191 individual values in a single cell, called cell objects, that can represent anything from simple lookup tables to complex polygons comprised of hundreds of coordinate pairs. Cell objects are continuously updated as changes are made to your worksheet and can either stand alone or be used as building blocks to form other cell objects.
