Hi All,

Does anyone know what the syntax error in this mod file is? It actually runs with dynare\_v3, but I get the following message with the latest snapshot of dynare\_v4 ( downloaded on 12-June-08 )

Configuring Dynare …  
[mex] Generalized QZ.  
[mex] Sylvester equation solution.  
[mex] Kronecker products.  
[mex] Sparse kronecker products.

Starting Dynare …  
Starting preprocessing of the model file …  
ERROR: kn08.mod:11.75-76: syntax error, unexpected LN, expecting NAME

Preprocessing failed

Thanks,

I guess it is due to the name of one variable “Ln” you specified. Dynare may use this name as a reserved name.
