Sorry - I didn't explain my problem very well. I need to find the *unknown* arguments of something like, t1 = beta1[y1] phi[y1,y2]; That is, t1 is a quantity generated in some code that I have written. If I am using Mma interactively, I can just type t1 (enter) and *see* what the indices of beta1 and phi are (in this case y1 and y1,y2 respectively). But within my program, I need a way of extracting the argument of beta1 from the expression t1. Any ideas?
