Disk No: 1284 Program Title: POWER SHEETS version 2.25E (Disk 1 of 2) PC-SIG version: 1 PC Magazine calls POWER SHEETS "the most powerful, pure spreadsheet on the market" and labels it "easy to use." Corporations such as Ford, AMOCO and First Chicago are using it to develop sophisticated turnkey applications beyond the capabilities of other spreadsheets. POWER SHEETS offers three-dimensional data presentations with the ability to rotate the data cube to view slices in other orientations. A special language gives POWER SHEETS programmability. Pop-up menus guide users through all functions. Other spreadsheets operate on ranges; POWER SHEETS goes further, using lists involving a combination of ranges, cell references, or formulae. Another feature allows it to base the bounds of a range on the values of other cells, and provides for true date and time math. All functions are fully recursive and can be nested to any depth. The upshot is the availability of 16 million cells. POWER SHEETS reads and writes DIF files either row-wise or column-wise. It reads and writes ASCII files either non-delimited or delimited with any choice of delimiters. Its rich function library includes trig and logarithmic functions, statistical and Boolean functions, yes-no-maybe logic, and sophisticated case function. Usage: Spreadsheet.
