Hello! AS code:

class MyClass
{
	int a;
}

MyClass v1;
v1.a = v1.a - 3;

I'm getting 'Expected identifier at column 3' for 'v1.a = ...' statement. Am I doing something wrong? (I'm on trunk)

Your code needs to be in a function. Column 3 is the point at which the compiler realizes something is wrong.

Exactly.

The global statements can only be used to declare global variables. You cannot perform general expression statements, as global statements.
