Hi,  
I am working on a DSGE model with many leads (expectations) and lags. Dynare generate auxiliary variables for them. I read in the forum that version 4.2.2 has bug in calculating steady state for those auxiliary variables, I has this problem too, so I switch back to version 4.2.1. This time I got the following error message:

Starting Dynare (version 4.2.1).  
Starting preprocessing of the model file …  
Substitution of endo leads \>= 2: added 21 auxiliary variables and equations.  
Substitution of endo lags \>= 2: added 10 auxiliary variables and equations.  
Found 48 equation(s).  
Evaluating expressions…done  
Computing static model derivatives:

??? Reference to non-existent field ‘maximum\_lag’.

Error in ==\> gnkpc\_nl6 at 493  
oo\_.endo\_simul=[oo\_.steady\_state\*ones(1,M\_.maximum\_lag)];

Error in ==\> dynare at 132  
evalin(‘base’,fname) ;

Can anyone help me figure out what is going on?

Thx

I also downloaded the latest unstable version 2011-11-21 to run my code. I still get the same error message:

There should not be a “clear all” in the file.
