data items, statements and declarations, organized into a program structure BASIC
or the Beginners AU-purpose Symbolic Instruction Code, was developed over a
period of years by professors John Kemeny and Thomas Kurtz and students in the
computer science program at Dartmouth College. It was released in 1965. In most
versions,
BASIC
is an unstructured language. The original Basic was easy to learn
allowing computer users to write simple programs within a few minutes.
Basic uses five major categories of statements:
– Arithmetical statements allow users to use Basic like a calculator
– Input/ Output statements, including READ, DATA, INPUT and PRINT
– Control statements including GOTO, IF-THEN, FOR, NEXT and END control
the sequence of instructions executed by the computer
– Other statements help document Basic programs and set up data dimensions
respectively
– System Commands tell the operating system how to work with Basic programs
RUN means execute a program
LIST directs the computer to display a Basic program.
