Let's assume that we have studied the problem, designed a logical plan, and are now ready to write the program instructions. The process of writing pro-gram instructions is called coding. The instructions will be writ¬ten on a form called a coding form. The instructions we write will be entered directly into computer memory through a terminal keyboard.
The computer cannot understand instructions written in just any old way. The instructions must be written according to a set of rules. These rules are the foundation of a programming lan¬guage. A programming language must convey the logical steps of the program plan in such a way that the control unit of the CPU can interpret and follow the instructions. Programming languages have improved throughout the years, just as computer hardware has improved. They have progressed from machine-oriented languages that use strings of binary Is and Os to prob¬lem-oriented languages that use common mathematical and/or English terms.
There are over 200 problem-oriented languages. One of them is PASCAL.
