Lotus 1-2-3

(tool, product)
A spreadsheet for MS-DOS from Lotus Development Corporation. It can be programmed using "macros" and comes with a separate program to produce graphs and charts but this cannot be run at the same time as the spreadsheet. It has keyboard-driven pop-up menus as well as one-key commands, making it fast to operate. Lotus 1-2-3 supported EGA and later VGA graphics. Early versions used the filename extension "WK1".

Version: 4.

Lotus 1-2-3 has been the subject of several user interface copyright court cases in the US.

Lotus 1-2-3

A popular spreadsheet for PCs, originally introduced for DOS in 1983. Later ported to many other platforms, including Windows, OS/2 as well as minis and mainframes, Lotus 1-2-3 became part of the IBM Lotus SmartSuite package. In 2013, SmartSuite was discontinued.

Why 1, 2, 3?
The name was chosen because it integrated spreadsheet, database and graphics. Lotus 1-2-3 was the first innovative spreadsheet for the PC and was launched with a huge marketing campaign. Its ability to function like a simple database was unique, and turning data into a chart with a single keystroke was dazzling for its time. The Lotus macros were the first macro language widely used in a spreadsheet. The software was supplemented with LotusScript, a BASIC-like language that supported Notes manipulation.
