Information functions generally return logical results and can be used in many business situations. Combined with other functions, the information functions can manage lists of data and provide feedback based on a logical result. For example, if you were tracking dates where certain items were received and then delivered, you could use the
ISBLANK function combined with the
IF function to return the result of numbers, widgets, or pages delivered. For a more in-depth explanation of this, see
"ISBLANK", later in this chapter. This chapter covers the functions in Table 11.1 that are marked in bold.
