Something like...

Code:
       FOR EACH $line IN $rc
          IF instr($line, "Destination Host Unreachable") OR @error<>0
             $status='DOWN'
          ELSE
             $status='UP'
          ENDIF
       NEXT
       $logdata=$i+','+$status+@crlf
       LOGGER($lf,$logdata)


Should return UP as long as the last reply is good. I guess if the last reply is no good then you would want it to be DOWN anyways right?
