Lotus 1-2-3 Release 9 is a spreadsheet application that became widely popular in the 1980s, and contributed to IBM’s success. The “1-2-3” in its name represented the program’s three main functions. Aside from enabling users to create spreadsheets for calculations and other processes involving numeric data, it can also help users generate charts and graphs from the data on the spreadsheet, and also create databases. The ninth release of the application enables users to set the criteria for each cell or cell range. This way, the type of data for the cells will be restricted to the ones that meet the set condition, preventing data entry errors.
This application contains a set of tools that make it easy for users to create and edit spreadsheets and databases. One of the key highlights is the InfoBox, a dialog box that enables users to apply formatting to a cell quickly and easily. Another feature of Lotus 1-2-3 Release 9 is its use of dynamic crosstabs, particularly in its Approach database tool. With this feature, users can group rows and columns to see the relationships between and among the different data types.
This program also enables users to copy spreadsheets, check spelling, create charts and maps, and automate repetitive procedures for faster operations. First-time users can access the Quick Demos to guide them in using the application. The Help menu also provides explanations in detail.
