The Software area has a number of Excel workbooks and software packages for various COGO operations

Excel workbooks

The workbooks may be used in their current form or modified as needed for educational purposes. They may not be used wholly or in part for commercial purposes. Each is provided as-is with no warranty against defects or errors and the author is not liable for any damages arising from their use.

Each workbook uses Visual Basic for Applications so marcos must be enabled in Excel when opening the sheet.
