The simple answer is:
myvars=Table[ToExpression["XX" <> ToString[k]], {k, 1, 10}]
However, working with created variable names like that can be quite
tricky because either they evaluate when you don't want them to, or you
end up assigning to an expression such as myvars[[5]], rather than the
variable itself.
For that reason, you may want to present a bit more of your problem so
as to get a complete solution.
