Create a Microsoft RTF report
Set up and configure output to Rich Text Format (RTF) from your reporting application. This option is useful if you want to edit your report after output.
Use fgl_report_selectDevice("RTF") to output the data in
            RTF format. Configure the output using fgl_report_configureRTFDevice. 
In order to prevent exhaustion of main memory when processing large documents, the processor can
            be instructed to swap parts of the document to a temporary disk file when the document
            size exceeds a threshold. Use the fgl_report_setRTFMemoryThreshold function to specify
            the threshold.
Example
#Produce an RTF document that contains pages 1 to 5 only
IF fgl_report_loadCurrentSettings(reportname) THEN
    CALL fgl_report_configureRTFDevice(1,5,NULL,NULL)
    CALL fgl_report_selectDevice("RTF")
    LET HANDLER = fgl_report_commitCurrentSettings()
ELSE
    EXIT PROGRAM
