Quick question about DirectX 9 shader globals.

Hello all,

I have a quick question about DirectX 9 shader globals.

Say you have two global variables in the shader ... is it technically ok to do the following:

int Level;
int TwoLevel = Level + Level;

So that when you change Level (via handle before rendering your batch) TwoLevel will be calculated accurately without accessing it?

Also, can you initialize your globals with calls such as pow/exp at the global scope level?

Thank you for your help.
