Macro-processors were prevalent when assembly language programming was the common tool of programmers. In these early days of programming, the programmers noted that much of their program was repeated text. Simple means to re-use this text were invented. Programmers soon discovered it easy to not only resuse entire blocks of text, but, on occasion, substitute different values for similar paramters. This defined the usage range of macro processors.
