The syntax diagram for the ReportLib.addReportParameter function is as follows:
ReportLib.addReportParameter( report Report in, parameterString STRING in, parameterValue any in)
Before filling a report, EGL can pass a set of parameters that either establish values to be used in the report or override parameters specified in the XML report design. The ReportLib.addReportParameter function adds the value of the specified parameter to the parameter list of the report.
