Add all variable names from a dataset to a matrix

[Bogdan]

The idea is that you can have a dataset with many variables so it would take much time writing each one by one.

How can you add all variable names from a dataset to a matrix, without explicitly writing each one by one ?

If there is no such defined option  (e.g. within use/read/close options), then is there a trick to do that?

proc iml;

use MyData;

read all var _NUM_ into X;
