Reading From and Writing To Files

Abstract

In this chapter we discuss TEX’s capabilities of reading from files and writing to files. Reading from files can be done in two different ways: a whole file can be read in using \input or a file can be read on a line-by-line basis using \read. A variety of macros relating to\input will be discussed such as macro \InputD which prevents a macro source file being read-in more than once. The chapter after this one continues the discussion with more on input and output such as writing table of contents and index files.
