Are you saying that I can infer (correctly?) that
AHI R1,X'FFFF'
results in an error because X'FFFF', taken as an expression, is not
in the range of 16-bit signed values?
But saying that an immediate datum must be an expression clarifies
a lot, because a data item containing a repetition factor is not
an expression.
