Hello Waldek

Great, that was it! 

works fine now (I was used to 'outputFom' but that's easy to me to change 
in my code).

Many, many thanks

   PhysQty is now explicitly exposed in frame initial
   PhysQty will be automatically loaded when needed from
      /home/scios/PQTY.NRLIB/PQTY

(1) -> pqty(100,10,%m(3))

                       3
   (1)  100.0 +- 10.0 m

                                                                Type: 
PhysQty
(2) -> )version
Value = "FriCAS 1.2.3 compiled at Wed, May 07, 2014  3:39:04 PM"
