Yes, I use that for temp variables only, it declares the variable as a temp so it can be referenced without the use of temp.

When you have variables defined in function parameters they're declared as temp variables and you're able to reference them with or without the temp. before the variable name, this is the same idea.

I place all the temp declarations at the beginning so I know what all I'm using and can make notes for other people using it.

Declares the variable, so it's value is "" not NULL.
