gEDA-user: problem in using models in gnucap



   Hi,
   I face a problem while using gnucap.
    If a model is used in circuit netlist and saved into a file errors
   are showing up.
   I copy the related output below:
   vsrks@vsrks-laptop:~$ gnucap

                                    ^ ? what's this?
   My question is whether default values are being used for simulation?
   Why default values are prefixed by NA.
   Am i supposed delete NAs if i want the default values to be used?
   (Though here i included only models of two devices,
   same error is seen in larger circuits)
