UnitStep[] Problem.

When I type in:
Table[UnitStep[x], {x, -3, 3}]

it should yield:

Instead, though, I get: 

Is this due to not loading a certain package? I've tried loading 
everything I could possibly imagine, and I've read over every bit of 
documentation I could scrounge up.  However, I've yet to have any luck 
getting it to work.

Oh, it's probably important to mention that I'm dealing with a 
considerably older copy of Mathematica: Mathematica Version 3.0.
However, it does appear that the UnitStep function should exist.

Thanks for any help.
