This article presents suggestions on writing computer software. It is worth reviewing some of the history of computer software to understand how programming came to be as complex as it is. Text, numbers, and instructions to the computer are all understood by the computer in pure binary number. Assembly language is far more readable than machine language, binary or box, but it is still a long way from being useful for complex computing. However, in the early 1950s, machine and assembly language were the only ways to program a computer. Structured programming continued to develop in the ensuing years, with languages such as LISP, Algol, Pascal, and C developing to meet specialized and general needs. Another high-level language similar to FORTRAN was Basic, developed as a simple, easy-to-learn language for college students who weren't programming oriented. Another form of simple programming is the macro, found in many programs from Microsoft Word to Adobe Photoshop. |
