AMPL doesn't support defining sets in a loop, or using string expressions
for their names. But you can write
set ABC {SET_U} within {SET_A,SET_B};
to define sets ABC[m] for each m in SET_U. There's an explanation of how to
use this construct in the discussion of "indexed collections of sets" in
section 6.5 of the AMPL book (page 100).
