System Unit

Closes an open file.

Declaration:

procedure Close(var F);

Remarks:
F is a file variable of any file type previously opened with Reset, ReWrite or Append. The external file associated with F is completely updated and then closed, freeing its file handle for reuse.

With {$I-}, IOResult returns zero if the operation was successful; otherwise, it returns a nonzero error code.

Example:

var
  Fi: Text;
begin
  Assign(Fi, 'C:\DATAFILE.DOC');
  ReWrite(Fi);
  WriteLn(Fi, 'A New File.');
  Close(Fi);  // Close and flush buffer to disk
end.
