Declares a file type for storing lines of text System unit
var TextFile;
The TextFile type defines a file type for holding textual data.
Text files provide a simple, convenient way of storing textual data. They do provide mechanisms for reading and writing numerical data stored as text (see Write), but it is safer and wiser to use structured records when storing anything other than plain text strings.
However, text files do allow variable length records.
