 ### Export Multiple Reports
 
-The technique demonstrated in this example allows you to generate and export different reports based on the same layout and data using different parameter combinations.
-Repeat steps 3 and 4 for each parameter combination.
+The technique demonstrated in this example allows you to generate and export multiple reports based on the same layout and data
+using a list of parameters.
+You need to initialize the report layout and data connection once (steps 1 and 2),
+and repeat steps 3 and 4 for each parameter.

 ```pas
-// Find each report parameter
-for AReportParameter in AReport.Parameters do
