I recently ported 90 pages of code from a competitor product -- mainly used by engineers -- to Mathematica for someone. The code was heavily subscripted because subscripted variables in the competitor product were pretty easy and essentially worked out of the box the way you would expect without a learning curve or any other issues. The were other reasons to justify the port to Mathematica but it was quite enlightening to see code in which subscripted symbolic variables were so natural and frankly made me wonder why Mathematica is behind the curve on this. Lets hope V9 offers this. Mike
