Raise an item in script

[Aetherius Shadowblade]

I want to make sure I get this right, so I am asking here.......
How do I put into a script to raise something? When I place an item, I have to raise it by 1 to look right, how would I do that?

Z++;

As Enroq said..

this.Z++;

..works, or you could also specify an exact increment like...

this.Z += 7;

thanks all.
my way would not have worked. I would have tried incz=1, but now I see that wouldn't work. glad I asked first.
