Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. FOCAL, is an interpreted programming language resembling JOSS. Largely the creation of Richard Merrill, FOCAL was initially written for and had its largest impact on the Digital Equipment Corporation's PDP-8 computers. Merrill wrote the original and classic FOCAL-69 interpreters for the PDP-8. Digital itself described FOCAL as "a JOSS-like language." Like early versions of BASIC, FOCAL was a complete programming environment in itself, requiring no operating system. As in MUMPS, most commands could be, and in practice were, abbreviated to a single letter of the alphabet. Creative choices of words were used to make each command uniquely defined by its leading character. Digital made available several European-language versions in which the command words were translated into the target language.
