One of the best business-oriented programs available for Timex/Sinclair computers is VU-CALC, a spreadsheet program by Timex.
Spreadsheets can be utilized in two ways: 1) as a calculation tool, to keep rows and columns of accounting-like figures organized; and 2) as a forecasting tool, to see the results of making changes to those figures (“What If…”).
The one drawback with VU-CALC is the sparseness of documentation provided with the program. A foldout sheet is included in the cassette box, but it does not explain the program’s functions in a clear manner.
But, a new book has been published that will take one through a step-by-step tour of both VU-CALC and VU-FILE (or “The Organizer”), Timex’s database program.
In “VU-CALC and VU-FILE”, Robert Masters give clear explanations of every command available for both programs. He also provides examples of actual applications that can be used almost immediately.
