For this discussion it's very important to know that literals of - for example -
length 4 will be aligned on word boundary due to literal sorting, regardless of
their type specifier and other attributes. This is what I've tried to explain in
my earlier posts.

That is

        L   R1,=XL4'55000000'

will work on S/360, because the literal is aligned, although XL4 normally does
not align definitions (with DS or DC, for example).

This may be clear to most of you, but maybe not to beginners, who follow this
discussion.
