Set file position to end of file
Source position: line 0
function SeekEOF( |
var t: Text |
):Boolean; |
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.
A run-time error is generated if the file F isn't opened.
