Beginners' All-Purpose Symbolic Instruction Code was developed at Dartmouth College in 1964. It is a high level programming language that was designed for ease of use and became a first programming language for many students. Microsoft's very first product in 1975 was a BASIC interpreter for the Altair 8800. In the microcomputer revolution that followed Microsoft BASIC became the built in language for many machines and saw wide use through the late 1980s.
For most systems, typing BASIC will start an interpeter and from there you can issue BASIC commands or type in STATEMENTS. BASICs on the various systems do have their own dialects and this page will attempt to point those out. On the IBM 4361 running VM/SP5 there is no interactive BASIC interpreter, but you can EDIT files and provide them as input to BASIC.
