| # Report scripts A report script allows you to customize the processing of the report. A report script consists of event sections in which you program actions to be performed at particular states of execution of the report. The statements programmed in a report script section consist of a combination of 3GL language statements and report script functions. You program report scripts in the same way as you program 4GL program scripts, except that report scripts use different event sections and some special functions. Report scripts allow you to: Perform additional queries Calculate complex print expressions Aggregate complex print expressions Update rows in the database Add fields from tables that are not queried by the program script, when you are not able to manipulate the program script Manipulate pre-defined variables in the report, such as if the layout should be printed or not.

Report sections can be processed before a layout, or after a layout. text field sections The report script is compiled automatically with the report when you compile the report. 注意 For details on Report scripts, refer to "Report Script Features" in the LN Programmer's Guide.
