Error while running dynare after pre processing is completed

I got this error after preprocessing section:

Starting preprocessing of the model file …
Found 15 equation(s).
Evaluating expressions…done
Computing static model derivatives:

  • order 1
    Computing dynamic model derivatives:

    Preprocessing completed.

Error: File: NK1.m Line: 236 Column: 1
Invalid use of operator.

Error in dynare (line 223)
evalin(‘base’,fname) ;

My Matlab is 2018a and dynare 4.5.4. and dont have problems with running dynare example 1. So it is not about versions and installation problem I suppse.

\\Exo variable
should be
//Exo variable

Thanks Now I have problems with finding steady state.

“Impossible to find the steady state. Either the model doesn’t have a steady state, there are an infinity of steady states, or the guess values are too far from the solution”.

What is general approach to solve it?

  1. Check all equations again.
  2. Provide better initial values
  3. Try computing the steady state analytically.
