Name
Append Procedure
Syntax
procedure Append(var F: TextFile);
Description
The Append
procedure opens an existing text file for writing. The initial file
position is the end of the file, so future writes append to the end
of the file.
The Append
procedure is built into the compiler.
For an example, see the AssignFile
Procedure.
Errors
If you have not called
AssignFile
beforeAppend
, Delphi reports I/O error 102.If the file cannot be opened for any reason, Append reports the Windows error code as an I/O error.
Tips and Tricks
Note that you cannot open a typed or untyped binary file for
appending—only text files. To append to a binary file, call
Reset
and seek to the end of the file.
