Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making specific disciplined use of the structured control flow constructs of selection (if/then/else) and repetition (while and for), block structures, and subroutines.

ALGOL 60 (short for Algorithmic Language 1960) is a member of the ALGOL family of computer programming languages. It followed on from ALGOL 58 which had introduced code blocks and the begin and end pairs for delimiting them, representing a key advance in the rise of structured programming. ALGOL 60 was one of the first languages implementing ...
This debate was closely related to language design: some languages had no goto, which forced the use of structured programming. To provide even faster compile times, some languages were structured for " one-pass compilers " which expect subordinate routines to be defined first, as with Pascal , where the main routine, or driver function, is the ...
BASIC (Beginners' All-purpose Symbolic Instruction Code) [1] is a family of general-purpose, high-level programming languages designed for ease of use. The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1963.
Much of the history of computer language design during the 1960s can be traced to the ALGOL 60 language. ALGOL was developed during the 1950s with the explicit goal of being able to clearly describe algorithms. It included a number of features for structured programming that remain common in languages to this day.
A programming paradigm is a relatively high-level way to conceptualize and structure the implementation of a computer program.A programming language can be classified as supporting one or more paradigms.
A key concept of structured programming is the local variable, which holds its value separate from other variables with the same name in other locations in the composite program. As BASIC did not have the concept of scope, many programs relied on the global behaviour and used variables to pass information in and out of subroutines.
