if A && B then
  "bingo"
elsif(A) then
  "bango"
elsif(B)
  "bongo"
else
  nil
end

This is just a guess, but you could also use a nested if or a case.
case(a)
  when !a | b then "a=t, b=t"
  when !(a & b) then "a=t, b=f"
  when !(a | b) then "a=f, b=t"
  when !a & b then "a=f, b=f"
end

But that would be wierd.
