Why not use ORG to do this for you?
ORG *,2,-1 take current position (*),
align to 2 byte boundary (if required), and move back one byte

I was trying to avoid generating an extra filler byte when one was not
required.

I'm writing a macro to build length prefixed character strings. The
length is one byte, and the actual string is referenced by LARL so it
needs to be halfword aligned.
So I coded (what would be a CNOP 1,2 - if it was valid):
DC (1-(*-&SYSECT)/2)X'00' Simulate a CNOP 1,2
However, this generates ASMA067S Illegal duplication factor.
what's wrong with DS 0H followed by DC X'00' or some such?
