and label designers, and a fully ANSI SQL compliant relational language capability. Since September 2007, R:BASE has been available as R:BASE for Windows v7.6, R:BASE for DOS v7.6 and R:BASE Turbo V-8 for Windows. The Version 8.0 has an extended address management for file handling and is able to cover databases up to 2.3 million TB versus V7.6 which covers databases up to 2 GB. A German kernel has existed since R:Base V7.6. Legacy R:BASE Products R:BASE 4000 The earliest version released by Microrim was called R:Base 4000 and was released in 1983. It worked with early version of Microsoft MS-DOS or IBM PC DOS (version 2 or above). It shipped with a binder-type manual and the program on 360KB floppy disks. The system being DOS-based, the interface was entirely text with the exception of DOS line-draw characters. In spite of its relative ease of use and ability to create useful forms and reports, the first R:Base did not have a conventional programming language, but instead relied on SQL statements to accept input and produce output. The lack of a complete programming language meant that the product was not well received by some portions of the market. This may have helped the early, barely relational, dBASE products to become dominant. The product was quickly upgraded to include Added Variables and a conventional programming Language (IF, WHILE, etc.) to the original SQL based language The update was released as R:Base 4000 Version 1.1 in March 1984. R:Base became the second most popular DOS database in the PC market (behind dBASE). Portions of the program allowed the user to design screens, called "Forms" in R:Base. Line-draw characters could implement buttons or boxes that would group text on screen. A separate utility allowed the design of printed output formats and was called "Reports." The report design system allowed a user to define and edit fields included in database reports on screen. Limited printer support was included as DOS programs each had their own unique printer driver for similar printer engines. A markup language allowed italics and bold output if the corresponding printer had a capability. Reports could be piped to the display or a serial port for testing if one were so inclined. Database names were constrained to seven characters. The actual data were contained in three files. In an example database named Sales, files name SALES1.RBF SALES2.RBF, AND SALES3.RBF would contain the
