Has it changed in > 4.0!? I have always found the way Mathematica handles subscripts rather neat (and it is just the same in 4.0). I wonder why you find such problems with the concept. - it really lets you do whatever you want with subscripts. For example, if you paste the following into your notebook (and execute it) you will cause all your subscripted 'a' s to be evaluated to a concatenated symbol: \!\(a\_i_ := Symbol[ToString[a] <> ToString[i]]\) As the above example illustrates, a subscripted expression is really analogous to f[i] - you can define it as a function or leave it unevaluated in algebraic expressions just as you wish. Do you have a specific example of something you wish to do? David Bailey, Salford Software
