Text files

A text file is simply a stream of characters.

• They contain human-readable text.
• The characters can represent numbers, words, or anything else.
• People can read and write them using a text editor

Text file structure

As far as Ada is concerned, there is no structure to a text file.

People see text as having structure, though:

• pages, of
• lines, of
• characters

Ada implements this structure by giving some characters special meanings:

• EOL - end of line
• EOP - end of page
• EOF - end of file
