Eof

Declaration:
Function Eof [(F : Any file type)] : Boolean;
Description:
Eof returns True if the file-pointer has reached the end of the file, or if the file is empty. In all other cases Eof returns False. If no file F is specified, standard input is assumed.
Errors:
Depending on the state of the {$I} switch, a runtime error can be generated if there is an error. In the {$I-} state, use IOResult to check for errors.
