BASIC implementations used by the small and simple home computers of the early 1980s.
They wanted to enable students in fields other than science and mathematics to use computers. It was intended specifically for less technical users who did not have or want the mathematical background previously expected. Being able to use a computer to support teaching and research was quite novel at the time. Wanting use of the language to become widespread, its designers made the compiler available free of charge.
The book remained popular, and was re-published on several occasions. 1970s was the start of explosive growth for BASIC. It had the advantage that it was fairly well known to the young designers and computer hobbyists who took an interest in microcomputers. BASIC was one of the few languages that was both high-level enough to be usable by those without training and small enough to fit into the microcomputers of the day, making it the de facto standard programming language on early microcomputers. 1977, all three had BASIC as their primary programming language and operating environment. The Apple II and TRS-80 each had two versions of BASIC, a smaller introductory version introduced with the initial releases of the machines and a more advanced version developed as interest in the platforms increased. As new companies entered the field, additional versions were added that subtly changed the BASIC family.
As the popularity of BASIC grew in this period, computer magazines published complete source code in BASIC for video games, utilities, and other programs. This book, and its sequels, provided hundreds of ready-to-go programs that could be easily converted to practically any BASIC-running platform. In addition they produced the Microsoft BASIC Compiler aimed at professional programmers. However, by the latter half of the 1980s, users were increasingly using pre-made applications written by others, rather than learning programming themselves, while professional programmers now had a wide range of more advanced languages available on small computers.
Return statements, and optional line numbers which could be used to locate errors. To the surprise of many at Microsoft who still initially marketed it as a language for hobbyists, the language came into widespread use for small custom business applications shortly after the release of VB version 3. 0, which is widely considered the first relatively stable version. By that time, computers running Windows 3. 1 had become fast enough that many business-related processes could be completed “in the blink of an eye” even using a “slow” language, as long as large amounts of data were not involved. Many small business owners found they could create their own small, yet useful applications in a few evenings to meet their own specialized needs.
Eventually, during the lengthy lifetime of VB3, knowledge of Visual Basic had become a marketable job skill. BASIC with DS button support. Japan November 2014, in North America October 2015, and in Europe August 2017. Exe2Bin and others are in these same directories. Basic variant known as Hummingbird Basic.
The VBScript variant is used for programming web content, Outlook 97, Internet Explorer, and the Windows Script Host. VBScript is one of the languages that can be accessed by the 4Dos, 4NT, and Take Command enhanced shells. Excel 4 and 5 use Visual Basic itself as a macro language. The ubiquity of BASIC interpreters on personal computers was such that textbooks once included simple “Try It In BASIC” exercises that encouraged students to experiment with mathematical and computational concepts on classroom or home computers.
