Lotus Development's successor to their Lotus 1-2-3 spreadsheet. Unlike 1-2-3, Symphony allowed a limited form of multitasking. The user could switch manually between it and MS-DOS and separate graph and spreadsheet windows could be opened simultaneously and would be updated automatically when cells were changed. In addition, a small word processor could be opened in a third window. These all could be printed out on the same report. Symphony could read and write Lotus 1-2-3 files and had interactive graphical output and a word processor, thus making it effectively a report generator. Unlike 1-2-3, Symphony was not a great commercial success.
