Hi,

Thanks for all the advices I received in the earlier post and I have
upgraded to VO 2.8 SP3. The first trial run is a breeze except for
this

oServer:CopySDF("ExportFile.dbf",NULL_ARRAY,{|x:=FALSE|
DataScope(oOwner,oServer)==TRUE}, {|x| .NOT. _field->( RECNO() ) ==
oOwner:_vFirstRec}, )

I disable this function (this runs prefectly in 2.6 which I have been
using for the last 4 years) and everything is running as usual on the
first look and am now starting to do extensive test. Can anyone assist
me on this?

Thanks

Try breaking it apart into discrete bits to locate the offending bit.

What happens in Datascope()??
Why are you equating LOGICAL values??
(DataScope(oOwner,oServer)==TRUE)

Why are you setting x := FALSE when you don't even use in the codeblock??
What's the _field->(recno()) for??
(wrong syntax imo - lose the () around recno() - that's a CLIPPER
requirement)

CYA

Dear Stephen

Thanks. It seems that x:=false is the culprit.

DataScope is a function to check certain fields. Only copy records
when it returns TRUE and stop copying when it reaches a predefine
recno of server.

With the change, it seems like working.
