#DEFINE cnOUTPUT_PRINT			         		2
#DEFINE cnOUTPUT_EMAIL			         		3
#DEFINE cnOUTPUT_FILE		 	         		4

LOCAL loFile
LOCAL lcReportFullName
LOCAL lcOutPutFileName
LOCAL lcOutPutFilePath
LOCAL lcFRX2AnyLibrary

CD LEFT(SYS(16,0), RAT('\', SYS(16,0)))

lcReportFullName = FULLPATH('..\..\Reports\Invoice.FRX')

IF !FILE(lcReportFullName)
	=MESSAGEBOX('File ' + lcReportFullName + ' does not exist.', 16, 'Error')
ELSE

	lcOutPutFileName = JUSTSTEM(lcReportFullName)
	lcOutPutFilePath = JUSTPATH(SYS(16,0)) + "\OutPut\"

	SET PATH TO  ..\..\..\
	
	lcFRX2AnyLibrary = 'FRX2Any'	 
	SET CLASSLIB TO &lcFRX2AnyLibrary IN FRX2Any.APP ALIAS FRX2Any			

	loFile = CREATEOBJ('FRX2Any.PDFFile')

	IF TYPE('loFile') = 'O'
*-- NOTE: loFile.cExportFileName should not include file extension. For example: loFile.cExportFileName = "ReportOutput"
		loFile.cExportFileName = lcOutPutFileName
*-- NOTE: loFile.cSaveFolder should contain only path to the output file. For example: loFile.cSaveFolder = "c:\MyApp\MyOutPut\"
		loFile.cSaveFolder     = lcOutPutFilePath
*-- Specifies that output file will be displayed after creation
		loFile.nOutPutType = cnOUTPUT_SCREEN
		
		loFile.SAVE(lcReportFullName)
		loFile.RELEASE()
