For non-relocatable values, the range of Y values is the same as a signed
halfword.
In my case, I want unsigned values so I can't use Y.
I ended up coding:
DC AL2(expr)
DS 0XL(65536-expr) ASSERT: expr was not truncated

H type constants, yes.
Y type constants, no.
They are address constants, addresses cannot be negative.
They date from the dawn of time, when there were 32K and smaller 360's abroad
