hi yehuda, mathematica 5.1 under os x. there's nothing syntactically (or otherwise) wrong with Table[{HoldForm[foo[i]], foo[i]}, {i, 5}] // TableForm but notice that it outputs foo[i] 1 foo[i] 4 foo[i] 9 foo[i] 16 foo[i] 25 which is not nearly as interesting as printing out foo[1], foo[2], foo[3], ..., in the left-hand column. anyway, treating "foo[" and "]" as strings in your second solution (and dr bob's solution) works perfectly. trevor.
