Here's the key block from a reporting framework I did recently for a client. It shows the elements that need to be set in the page table.

pageTbl^.responseBody = EvenStartSuite.reports.generateReport( reportName, postArgsAdr, requestedFmt );
pageTbl^.responseHeaders.["Content-Disposition"] = "attachment; filename=" + GenFilename( now );
pageTbl^.responseHeaders.["Content-Type"] = "text/" + requestedFmt;
pageTbl^.responseHeaders.["Last-Modified"] = date.netStandardString( now );
EvenStartSuite.utils.DisallowHTTPCaching( pageTbl );
«Short-circuit all remaining processing and just return the content.
scriptError( "!return" )

In this application, /requestedFmt/ may be "xml", "html", or "csv".

You may or may not want to turn off HTTP caching. If so,
DisallowHTTPCaching looks like this:

on DisallowHTTPCaching( pageTbl=nil ) {
 if pageTbl == nil {
 pageTbl = html.getPageTableAddress()};
 pageTbl^.responseHeaders.Pragma = "no-cache";
 pageTbl^.responseHeaders.["Cache-Control"] = "no-cache"}

HTH.
