CHAPTER 24 DataWindow Expression and InfoMaker Functions
Users Guide 639
When you preview the report, notice that the first computed field displays null
for ABC Corporation and XYZ Corporation. The second computed field
displays the first part of the address, which is not null.
Other examples
In InfoMaker, to see some examples of using functions, examine the reports
and forms in TUTOR_IM.PBL, which is InfoMaker’s sample library. The
reports and forms were created using data in the EAS Demo DB.
Look carefully at the reports whose names begin with attrib_. Each report is a
good example of the use of functions in expressions. And look at the design of
each report and form in the sample library to see the use of functions in other
ways.
For more information
For examples of using expressions to control the value of properties at
execution time, see the chapter on highlighting information in reports in the
Users Guide.
For an example of the use of each InfoMaker function, see the function
descriptions that follow.
