Document Summary
Executable statements are any operations that are executed by the program. An instruction that stores a value or a computational result in a variable. Form of an assignment statement variable = expression. E. g. a = 7 * 8 + z. A variable can appear on both sides of the assignment operator. I/o function is any function that does input/output. Input operation is an instruction that copies data from an input device into memory. Output operation is an instruction that displays information stored in memory. Calling a function is the activation of a function. Function arguments are values called to the function during the function call to provide needed information. Transfers control of the program from the function which it is in to the activator of the function. It returns a value when the control is transferred. At least one black space is required between words in a program, but additional are ignored by the compiler.
