How can you create a set of variables: x1 to xn using the Table, or some similar function? I need a large list of variables to use in a linear program and so far have to type them out manually. David One easy was is for example ta = Table[Subscript[q, j], {j, 10}]. This gives you 10 subscripted variables. Then you can do the usual operations such as Subscript[q,5]=7 . Then ta is {Subscript[q, 1], Subscript[q, 2], Subscript[q, 3], Subscript[q, 4], \ 7, Subscript[q, 6], Subscript[q, 7], Subscript[q, 8], Subscript[q, \ 9], Subscript[q, 10]} It is easier to bring up the Basic Math palette and use it to make the subscripts rather than using Subscript[ ].
