If all three dimensions are specified, the leftmost dimension defines pages, the middle dimension defines rows, and the rightmost dimension defines columns. If two dimensions are specified, the left defines rows, and the right defines columns. If a single dimension is specified, it defines columns. A dimension expression is composed of elements and operators. Cross a format modifier with the elements that produce the cells that you want to format.
ALL labels temporarily replace the names of variables and statistics.
Labels affect only the variable or statistic that immediately precedes the label. For details, see Specifying Style Elements in Dimension Expressions . You can also form dimension expressions by combining any of these elements. If one of the elements is an analysis variable, the statistics for the analysis variable are calculated for the categories that are created by the class variables. This process is called crossing .
