  Visual Basic’s Background
  By understanding the background of Visual Basic, you’ll gain insight into Visual Basic 6
  and you’ll be better equipped to use Visual Basic. Microsoft based Visual Basic on a
  programming language written for beginners called BASIC. BASIC has been around for
  more than 35 years in one form or another. The original language designers wanted to
  develop a programming language that beginners could use. With BASIC, new
  programmers could become proficient right away. Other programming languages of the
  day, such as COBOL, FORTRAN, and Assembler, required much more study than BASIC
  before one could use them effectively.

  BASIC stands for Beginner’s All-purpose Symbolic Instruction Code. That’s
  some abbreviation!
  A programming language is a set of commands and command options, called
  arguments, that you use to give instructions to the computer. Computers cannot
  (yet) understand human languages because people deal well with ambiguous
  commands, and a computer cannot understand such ambiguity. A programming
  language must be more precise than a spoken language.

  Although the BASIC language was designed for beginners, a BASIC program was still
  rather cryptic and required study. Listing 1.1 shows a program written in BASIC. The
  program’s goal is to print the mathematical squares for the numbers 1 through 10.
  Although you can probably guess at many of the program’s logic and commands, the
  program is certainly not the clearest piece of literature in the world and requires that you
  understand BASIC before you can fully comprehend the reason for all of its elements.

  Microsoft did not create Visual Basic directly from the original BASIC
  language. Although the BASIC language evolved through several stages over
  its 35-plus year history, it kept its original structure in most of its incarnations.
  When Microsoft decided to use BASIC as its primary programming language
  supplied with the original MS-DOS operating system, however, it honed the
  BASIC language and added functionality to BASIC by creating several
  incarnations of BASIC with names such as MBASIC (for Microsoft BASIC),
  GWBASIC (for, some say, Gee-Whiz BASIC), BASICA (for BASIC
  Advanced), QuickBASIC, and QBasic (which is still supplied on Windows
  operating system CD-ROMs).
  Throughout BASIC’s evolution, the BASIC language kept its simple nature
  while gaining powerful new commands along the way. The text-based nature
  of languages such as QBasic helps new programmers get up to speed more
  quickly than many nontext languages such as Visual C++ do. To maintain this
  ease of use, Microsoft wanted to keep all its BASIC language versions
  interpreted in nature as opposed to compiled. A programmer can execute a
  program based on an interpreted language immediately and see results and
  errors instantly. Such feedback is critical for beginners who need a quick
  response when learning how to program. Compiled languages, although they
  run faster and are better suited for commercial program development
  environments, require much more effort to work with......
