syntax error, unexpected COMMA, expecting EQUAL or '.'

[0130535]

When I use the example of p56 of DYNARE User Guide,the dynare said error:
why/

estimated params;
alpha, beta_pdf, 0.35, 0.02;

Please provide the full file.

the original program is :

var y c k i l y_l w r z;
varexo e;
parameters beta psi delta alpha rho epsilon;
model;
(1/c) = beta*(1/c(+1))*(1+r(+1)-delta);
psi*c/(1-l) = w;
c+i = y;
y = (k(-1)^alpha)*(exp(z)*l)^(1-alpha);
w = y*((epsilon-1)/epsilon)*(1-alpha)/l;
r = y*((epsilon-1)/epsilon)*alpha/k(-1);
i = k-(1-delta)*k(-1);
y_l = y/l;
z = rho*z(-1)+e;
end;
varobs y;
initval;
k = 9;
c = 0.7;
l = 0.3;
w = 2.0;
r = 0;
z = 0;
e = 0;
end;
steady;

why? thanks!

You are missing the underscore in estimated_params and first_obs.
