# How to create a list of variables and reference them?

I was trying to create a list of n variables such as x = Table[Symbol["x" <> ToString[i]], {i, 5}], which be done by using Symbol. However, if after that, I want to assign values to those variables, I could not figure out how to properly reference a variable using x and an index (I prefer this method because I may need to reference the variables in a loop). For example, in the code that follows, x[] = 5 does not assign the value to x1. How could I reference x1 properly using x and an index? • How about just using x, x, etc. as variables? (after Clear[x] I mean). I think making a list of variables and then trying to refer to them is needlessly complicated. Jan 29 '20 at 21:27
• @Roman Good point. By using x, x, ... and then assign them values, it is essentially defininga function x with some discrete values, right? Jan 29 '20 at 21:36
• Colloquially speaking, yes. Strictly speaking, there are no functions in Mathematica, and you're assigning DownValues to the symbol x. Jan 29 '20 at 21:43

While I would suggest indexing using arguments (x, x, ...), you can simply add Evaluate on the lhs of the assignment as

x = Table[Symbol["x" <> ToString[i]], {i, 5}]
Evaluate@x[] = 5
x
x1


{x1, x2, x3, x4, x5}

5

{5, x2, x3, x4, x5}

5
