Since APAR PH40885 you can simply suppress warning ASMA500W if you don't want to be nagged about item alignment exceeding SECTALGN, as the alignment warning no longer prevents the expected code from being generated.
The section alignment for purposes of code generation is now always assumed to be as strong as is needed, but the binder alignment option is set based on SECTALGN and the warning is issued if item alignment exceeds the binder section alignment. Jonathan Scott, HLASM IBM Hursley, UK
