UnitStep[] Problem.

  • To: mathgroup at smc.vnet.net

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

it should yield:
{0,0,0,1,1,1,1}

Instead, though, I get: 
{UnitStep[-3],UnitStep[-2],UnitStep[-1],UnitStep[0],UnitStep[1],UnitStep
[2],UnitStep[3]}

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.
