TQRExpr. Use this to display the result of an
arithmetic expression. Typically you use one of these when you need
to massage the appearance of your data before printing it out. The
best way to think of these is as ad hoc calculated fields, used
only in the report. For example, you might use it to concatenate
the parts of a customer name, held in a customer table as string
fields called “Title”, “Forename” and “Surname”.
To do this simply set the Expression property of TQRExpr to
Title + " " + Forename + " " + Surname
In real life, you would probably use a more complex expression
to cope with blank fields elegantly, but you get the idea.
