Do you mean to a halfword boundry? === Yes, it is an interesting idea and, IMHO, the only way to implement it would be exactly like a DS0H. It's only purpose would be to label executable machine instructions, so interleaved assembler instructions would have no impact. === > Date: Thu, 14 Jun 2012 10:38:18 -0500 > From: john.mck...@healthmarkets.com > Subject: Re: DS 0H > To: ASSEMBLER-LIST@LISTSERV.UGA.EDU > > Well, just my personal oddity, I guess.
