The value of a constant never changes, so Crystal takes advantage of this fact to define several formatting and calculation values for you. You can use these constants in code or in drop-down boxes to make choices in the various Expert dialogs provided.

• Boolean Conditions: on any change, on change to yes, on change to no, on every no, on next is yes, on next is no

• Colors: Color constants appear in the Function Tree when a formatting formula is being coded; this is shown in Figure 4.40. To use any of the colors in code directly, preface the color name with a cr, for example, crRed.
