Report Writer Built-in Functions
The Report Writer built-in functions have two main purposes. Some of
these functions retrieve information Report Writer has kept for you, such
as the automatic totals. Other functions help you control Report Writer
flow and output.
Unlike the Report Writer statements, the Report Writer built-in functions
are used in subunits other than the one containing the report.
The functions are listed in Table 7-1, along with a brief description.
They are defined and explained in chapter 5.
