Example
The following example determines whether the specified file exists. If it exists, the WriteMode Method (File) allows the file to be open for writing. The Open Method (File) opens the file, the Write Method (File) writes the text “Hello World” to the file, and then the Close method closes the file. If the file does not exist, an error message is displayed. This example assumes that you have created the following file C:\TestFolder\TestFile2.txt.
var
FileName: Text;
TestFile: File;
begin
FileName := 'C:\TestFolder\TestFile2.txt';
if Exists(FileName) then begin
TestFile.WriteMode(true);
TestFile.Open(FileName);
TestFile.Write('Hello World');
TestFile.Close;
end else
Message('%1 does not exist.', FileName);
end;
