User Features 1-2-3 The name derives from the integration of three major product capabilities. In addition to being a spreadsheet, also integrated graphics and the ability to perform rudimentary or basic database operations (primarily from its search function VLOOKUP tables, very similar to the VLOOKUP would implement later Microsoft Excel .) The characteristics of data such as the ordering of any defined range (for example, one or two columns within a rectangular area). The justification of text in a range in different paragraphs allowed to use 1-2-3 as a primitive or or word processor. Also had floating or emergent menus (pop-up menus) are accessible using the keyboard as well as “hot keys” or shortcuts (shortcuts) that allow rapid operation of the program.He was also one of the first programs to be user friendly (user friendly), offering the user-after pressing the F1-help depended on the context. Macros and add-ins (introduced in version 2.0) contributed greatly to the popularity of 1-2-3, allowing dozens of outside suppliers of software offer additional packages ranging from dedicated spreadsheet (eg specializing in Financial Management) to ing capabilities that at times made it seem the program as a word processor. Thus, in a multitasking operating system such as MS-DOS, 1-2-3 came to be used as a kind of “environment” working quite complete. Lotus 1-2-3 supported a resolution EGA (Enhanced Graphics Adapter) on the platform PC / AT and VGA in the PS / 2, which IBM launched in 1987. Early versions used the file extension “WKS.” . In version 2.0, firstthe extension changed to “WK1”, and then go to “WK2.” .The latter became WK3 for version 3.0 and “WK4” for version 4.0. Version 2 introduced macros with syntax and functions similar in complexity to an advanced BASIC interpreter, which included handling expressions of type string (strings). Later versions stand the use of multiple sheets or spreadsheets into one single binary file (like the later books or workbooks in Excel and Quattro Pro notebooks) to others are rewritten in C. This permitted the programming times are shortened enough, since C is a kind of language “intermediate” between the assembler and high level, including a memory management as straightforward as the assembler, but with the versatility and convenience to of the latter. There is also a specific version of 1-2-3 for the HP 200LX, a palmtop released by Hewlett-Packard as well as a version or port for Tandy Deskmate.
