how do I query a world position of

always to get/set the translate, rotate, scale attributes for anything use xform command.
eg. to get the tx,ty,tz for curve1.u[0.2] in worldspace write

float $translate[] = `xform -q -ws -t curve1.u[0.2]`;
so $translate[0]=translate on x, $translate[1]=translate on y and $translate[2]=translate on z

thank yashu, I've tried that, but unfortunately the value returned is allways 0 0 0. Anyway, I've figured out how to do it. The trick is in the `pointOnCurve` command.
The solution for my problem is:

pointOnCurve -pr 0.5 -p curve1;

the x y z world coordinates are returned...

hmmm glad you've got-it. Don't know why you get 0 0 0 cause it works for me, maybe you're missing the -ws flag

edit :: yeap xform doesn't work with point curve, only with movable things
