How to see the output under the changing of temperature?

[dunv]

Now,I am designing a CMOS bandgap voltage reference in hspice. It's been asked to sweep temperature from 0 to 100 degree and the vdd changing from 3.3v to 5v.
I set:
.dc temp 0 100 0.1 vdd 3.3v 5v 1.7v
.tf v(vo) ??
.probe v(vo)
but I don't know what's the words I could put in the place of ??
If you have other better method to get this result,Please teach me.
Best regards!

.tf v(vo) v(vin)
where vin is your input supply
but whay you don't use .alter ?
is more simple

.param SP = 3.3
.dc temp 0 100 0.1
.alter
.param SP=5

in this mode you will have 2 simulations results for each of your SP (supply power) 3.3 and 5 v
