Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
What allowed LINC to make programmers much more efficient and the application systems they produced easier to read and maintain, and differentiated it from being simply yet another third generation high level language, was LINC's assumption, use of, and total reliance on all of the facilities available, and packaged, with the Burroughs computer ...
