An optional END attribute may be used after the last data item.
If USING is not specified, then END:
1) suppresses the EOL sequence from being output after the last item,
2) sends an EOI signal with the last character of the last item sent to an IEEE-488 device, and
3) truncates a file. A comma before the END will output an item terminator (a comma for numeric items or a CR/LF for string items).
For example:
OUTPUT @I;"Time: ";TIME$(TIMEDATE) END
