Hmmm, I can't quite see what you are after here. Do you want to change the values of a[i] afterwards and have them appear in b? If so, why not include an argument for a in b. In any case, if you do this Do[a[i] = i, {i, 10}] Do[b[i_] := a[i] + 1, {i, 10}] (The second do contains 9 redundant definitions!!!!!!!!!) Then, b[6] will be 7, b[23] will be 1 + a[23] and a[2] = YooHoo; b[2] will be 2 + YooHoo
