Jonathan, I apologize if this solution is way too obvious and you may
have something else in mind. Have you considered an array?

t = fltarr(10)
t(0)
t(1)
t(2)
If the values all need to be of different types, then pointers come to
the rescue.
t = ptrarr(10)
t(0) = ptr_new(0.5)
t(1) = ptr_new('hello')
t(2) = ptr_new(dblarr(100,400)
print, *t(0)
print, *t(1)
and so forth

Plus you can extend the length at will
t = [t, ptr_new('extension works')]
or remove elements, retaining only some.
t = t([1, 3, 4])

Is there a reason why this wouldn't work for you?

M. Katz.
