OK, so here's what that code looks like:

#DEFINE xlCSV 6
* or
#DEFINE xlCSVWindows 23

loExcel = CREATEOBJECT("Excel.Application")
loExcel.Workbooks.Open("c:\setup\tabledatabufflab.csv")
loExcel.Workbooks.SaveAS("c:\setup\tbdata333.csv",8)  
loExcel.Workbooks.Close(0) 
loExcel.Quit

I get an OLE error that says 'Unknown Name'. (I tried changing the '8' to '6' or '23' and got the same).....
