#### Append

Declaration:
  Procedure Append (Var F : Text);
Description:
  Append opens an existing file in append mode. Any data written to F will be appended to the file. Only text files can be opened in append mode. After a call to Append, the file F becomes write-only.

  File sharing is not taken into account when calling Append.

Errors:
  If the file doesn’t exist when appending, a run-time error will be generated. This behaviour has changed on Windows and Linux platforms, where in versions prior to 1.0.6, the file would be created in append mode.

{ Program to demonstrate the Append function. }
Var f : text;

Assign (f,'test.txt');
Rewrite (f); { file is opened for write, and emptied }
Writeln (F,'This is the first line of text.txt');
close (f);
Append(f); { file is opened for write, but NOT emptied.
any text written to it is appended.}
Writeln (f,'This is the second line of text.txt');
