The TStringList class has LoadFromFile and SaveToFile functions that you can use for that:
Code: Select all
function GetLocalFile(Path: string): string;
var
File: TStringList;
FileName: string;
begin
File:= TStringList.Create;
FileName := Path;
Input('', 'File to read:', FileName);
File.LoadFromFile(FileName);
Result := File.Text;
File.Free;
end;
This is a demo function. If you want to process it line per line, you can of course directly use the TStringList object (named "File" here)
