A set of simple text input/output routines for Praxis entitled Textio are described. This package allows arrays of characters to be written to/from files and serial I/O devices. It is a straightforward set of definitions and procedures which accomplish reading and writing characters and lines of text. The Textio package is written in Praxis. It interfaces to the particular operating environment via the module Macio. Macio is usually written in the assembly language of the target machine. The data type and Textio definitions are discussed, and the simple and easy to use procedures are described fully. (WHK)
