How about ?

PROCEDURE SomeProc
LOCAL SomeVariables, lRet, nX

DO CASE
   CASE !THIS.GetValidDateRanges()

   CASE THIS.ExecSomeOtherCode() AND TYPE('.arrItems[1,1]')#'N'

   OTHERWISE
      nX = 1
      lRet = .T.

      DO WHILE nX >= ALEN(THIS.arrItems,1) AND lRet
         lRet = (THIS.arrItems[ix,2] # 'somecondition' OR THIS.SomeOtherProc(nX)) AND ;
                (THIS.arrItems[ix,3] # 'somecondition2' OR THIS.SomeOtherProc2(nX)) 

         nX = nX + 1
      ENDDO
ENDCASE
RETURN lRet

Compact, and in some respect somewhat dirty. However I find this very clear to read.
