When we put variables
in our tables, PROC TABULATE adds labels for the appropriate rows
or columns that indicate which variable is being displayed where.
But variable names are not always very descriptive. The variable name
OCCUP might be clear to you, but people reading your table might be
confused by this cryptic label. A better approach is to use a descriptive
label for your variable. There are two ways to do this. You can use
the LABEL and KEYLABEL statements, or you can use the TABLE statement.
