Paula,

No, a dataset has a rectangular sturcture, that is all records have the same
variables (columns). If you want to DROP variables you drop them in the
whole dataset. The only thing you may do is to conditionally redefine
(reassign) values to specific variables, i.e. missing values.

Regards - Jim.
