Reset

(Under construction.)

Synopsis


procedure Reset (var F: any_file; [FileName: String;]
                                    [BlockSize: Cardinal]);

Description

Reset opens an existing file for reading. The file pointer is positioned at the beginning of the file.

Like Rewrite, Append and Extend do, Reset accepts an optional second and third parameter for the name of the file in the filesystem and, for untyped files, the block size of the file. (For details, see Rewrite.)

Conforming to

Reset is defined in ISO 7185 Pascal. The BlockSize parameter is a Borland Pascal extension. The FileName parameter is a GNU Pascal extension.

Example


program ResetDemo;
var
  Sample: Text;
  s: String (42);
begin
  Rewrite (Sample);  { Open an internal file for writing }
  WriteLn (Sample, 'Hello, World!');
  Reset (Sample);  { Open it again for reading }
  ReadLn (Sample, s);
  WriteLn (s);
  Close (Sample)
end.
