SeekEof

Declaration:
Function SeekEof [(Var F : text)] : Boolean;
Description:
SeekEof returns True is the file-pointer is at the end of the file. It ignores all whitespace. Calling this function has the effect that the file-position is advanced until the first non-whitespace character or the end-of-file marker is reached. If the end-of-file marker is reached, True is returned. Otherwise, False is returned. If the parameter F is omitted, standard Input is assumed.
Errors:
A run-time error is generated if the file F isn’t opened.
