What is missing for enforement of value in Excel Spreadsheet...
Here's my partial code

   oExcel=CREATEOBJECT("Excel.Application")
   With oExcel
      .DisplayAlerts= .F.
         .WorkBooks.Open(ALLTRIM(Charttabs.Sheet),0)
         .Sheets(ALLTRIM(Charttabs.Tab)).Select()
         DO PopulateExcelArray
      .Quit
   EndWith
   Release oExcel

Procedure PopulateExcelArray 
... && no problem retrieving information from spreadsheet
      cRange= "A"+ AllTrim(Str(nRow)) && Column A4
      .Range(cRange).Select()
      &cArray(nRow,iColumn)= AllTrim(DTOC(.Range(cRange).Value))
...
   DO ProvideDesc
EndProc

PROCEDURE ProvideDesc
... && no problem getting a description into my array
   cDescription= cDescription+ ALLTRIM(IIF(ISNULL(.Range("AE3").Value)," ",AllTrim(TRANSFORM(.Range("AE3").Value))))
   &cArray(2,26)= cDescription
   DO UpdateSpreadsheet

PROCEDURE UpdateSpreadsheet
... && no problem to identify new values for spreadsheet
            sRowID=ALLTRIM(STR(&cArray(3,1))
...
            sAE= CHRTRAN(CHRTRAN(sAE,CHR(9),""),"-","")
... && What must be added to enforce this cell, say A199, to be populated?
            IF !EMPTY(sA)
               cCell="A"+sRowID
               .Range(cCell).Select()
               .Range(cCell).Value= CTOD(sA)
            ENDIF

Do I have an object.update missing? Where can I get a list of Excel Object interactions?

TIA
