ORG *,8 doesn't do anything that DS 0D doesn't do, but ORG *,256 has no DS equivalent.
The syntax diagram in the HLASM reference shows ORG ,8 to be invalid syntax, so there is no way that the message could be legitimate; there should have been a message for syntax error. Of course, it would be nice if there were valid syntax for specifying high water mark with alignment. -- Shmuel (Seymour J.)

Wouldn't "DS 0D" be more typical for "I want the next thing to be on a doubleword boundary? It certainly is for those of us who learned assembler long before SECTALGN (and this form of ORG) even existed. It might be true that the ASMA500W message is not the write message for "ORG ,8" but that is assuming that you know what boundary is being processed for such a case. The "null" first operand might have some effect on things. Or maybe it really is just a parsing glitch (and is an error).
