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.
Example code : Writing to and reading from a TextFile
myFile : TextFile;
text : string;
begin // Try to open the Test.txt file for writing to
ReWrite(myFile); // Write a couple of well known words to this file
WriteLn(myFile, 'Hello World'); // Close the file
CloseFile(myFile); // Reopen the file for reading
Reset(myFile); // Display the file contents
while not Eof(myFile) do
end; // Close the file for the last time
