vex vector attributes

[freaq]

I'm probably being very stupid, and a total n00b with vex so please bear with me.

all this is currently in an attribute wrangle.

 

basically I want  to create a new vector attribute

and I want it to be the location of a point. (another point not p)
I already have an attribute for it that is a vector called position.

I can do:
 

@Cd = position;

works fine

 

vector @test = {0,0,0};

works too

 

but I cannot do
vector @test = position;

vector @test = {position};

vector @test = {position.x,position.y,position.z};

 

also I can't seem to get the printf to work.
all help is greatly appreciated!!!

if position is vector variable, then it would be:

 

v@test = position;

 

if position is an attribute then:

v@test = v@position;
