The Markup Language
The idea of using markup language, in which meta-information about the document and its formatting were contained within the document itself, first saw widespread use in a program called RUNOFF; Scribe contained the first robust implementation of declarative markup language.
In Scribe, markup was introduced with an @ sign, followed either by a Begin-End block or by a direct token invocation:@Heading(The Beginning) @Begin(Quotation) Let's start at the very beginning, a very good place to start @End(Quotation)
It was also possible to pass parameters:@MakeSection(tag=beginning, title="The Beginning")
Typically, large documents were composed of Chapters, with each chapter in a separate file. These files were then referenced by a master document file, thereby concatenating numerous components into a single large source document. The master file typically also defined styles (such as fonts and margins) and declared macros like MakeSection shown above; macros had limited programmatic features. From that single concatenated source, Scribe computed chapter numbers, page numbers, and cross-references.

Famous quotes containing the word language:
“I am both a public and a private school boy myself, having always changed schools just as the class in English in the new school was taking up Silas Marner, with the result that it was the only book in the English language that I knew until I was eighteenbut, boy, did I know Silas Marner!”
—Robert Benchley (18891945)
