The reason that I could not clearly express my question was that I was trying to translate structure of arrays in C to VEX tamte.

The answer by Obeida Zakzak is similar to what I am looking but I am not very sure.

I will try to experiment with the answers and come up with better description.

Thanks to anyone responding.

I am aware of it and your solution does not help neither.

I do not know the index of the points(@ptnum) and the algorithm will dictate which points will be qualified.

I am looking for a procedure that will affect only some of the points of the geometry but I do not know which points exactly and the index of the points are the result of some searching and other computations.

Thanks but this is not possible when I do not know the points in advance. My question is about situation that is not predictable. For example there is an if statement and we want to change some attributes for those points.

How can I enter that procedure to the body of vex?
