A Boolean expression evaluates to True or False. For example, consider a calculated column displaying values for the following expression:
If the actual ship date is before or on the target ship date, the expression evaluates to True. If the actual ship date is after the target ship date, the expression evaluates to False. If you do not format a column of Boolean data type, the column displays the values True and False. To specify different labels, select the column, and from the context menu, choose Format→Format Data. Type the new labels on Boolean column format, as shown in Figure 3-15.
