'	This script assumes that the Session contains the following Crystal Report Engine
'	Objects:
'
'	"oApp" - Crystal Report Engine Application Object
'	"oRpt" - Crystal Report Engine Report Object
'	"oPageEngine - Crystal Report Engine Page Engine Object
'	HTML_FRAME viewer only
'	"tabArray" -  Array used to keep drilldown tab information
'	"CurrentPageNumber" - Current Page Number requested.
'	"lastknownpage" - Previous page number requested.
'	"LastPageNumber" - Last known page number requested.
'	Note:  Before creating the PageEngine object, call ReadRecords on the 
'	report object to that all the database records have been read.
'
'	Modifications
' 05/02/98
' Added the following features:
' Tab Query String Parameter
'	- This is the selected HTML_FRAME viewer tab's tabArray index value.  
' Page Expiry Time
'	-  The page will expire when downloaded by browser so that user is insured that all data
' will be current.
' DrillDown Tabs
'	- Added in the session("tabArray") object to keep track of the HTML_FRAME drill down tabs.
' RFSH Query String Parameter
'	- Database is refreshed and ErrorValue 0 is sent to Java and active X viewers on success.
'This causes viewers to NOT refresh browser window.
' SRCH Query String Parameter and HTML_FRAME Viewer
'	-  Added javascript window.alert function call to indicate when text is not found in rpt view.

' 09/08/98
' Added the following features:
'	- cmd handling for map_dd(Map Drill Down) and export(Exporting reports from viewers).
'	- PageGenerator object creation for Out of Place Subreports.  Modification was made to RetrieveObjects procedure.
'	- Modified the get_ttl handling to call the PageGenerator object's RenderTotallerETF method 
'		instead of the PageEngine's method.  This was done to support the group by feature.
' 08/03/99
' Added the following features
'	- cmd/rfsh handling for pages with and without place holders.
'	- cmd/rfsh handling for pages requiring and not requiring total page count.
' 08/08/00
' Added the following features
'   - Export to excel 7.0 and portable document format(.pdf).
'	- Removal of WCS dependency.  We are now using emfgen to send images to browser.
