Cetin, even after the change you suggested I am still getting the following
error:

OLE IDispatch exception code 0 from Microsoft Excel: Unable to get the Paste property of the Worksheet class..

SELECT c_sum2

lcFile = SYS(2015)+".TXT"
COPY TO (lcFile) DELIMITED WITH TAB
_CLIPTEXT = FILETOSTR(lcFile)
ERASE (lcFile)


USE IN c_sum2

WITH .oExcel.ActiveWorkBook.ActiveSheet
.Range("A1").Select()
.Paste()
ENDWITH


>>I should have also include that the error number was '800a01ad'

>>>The following code works without any issue in a regular VFP Class:
>>>
>>> SELECT c_sum2
>>> GO TOP
>>> Application.DataToClip(,,3) && copy data to clipboard delimited with tabs
