The filter window allows you to determine which variables will be displayed in the list of variables. The window allows you to filter inactive variables or variables currently out of order and have no interest in showing them. The four buttons at the top of the window will enable you to perform the following functions:
View all currently hidden variables.
Hide the variables marked in the list.
Presentation of all the variables. That is, removing all display restrictions.
Hide all variables.
Setting the display policy does not affect the processing of the variables.
