Thank you for your expert advice!It worked but there is still one question...
The results differ from what my coauthor obtained from RATS/GAUSS. What we did was solving
non-linear equations rendered by imposing short and long-run restrictions simultaneously.
We computed the reduced form VAR and its covariance matrix. Then, we computed and
combined the short-run restriction (contemporaneous) matrix and long-run restriction
matrices in the Structural Moving Average presentation. Then, the two combined matrices
were compared with the covariance matrix to estimate needed coefficients. This part of
solving multiple non-linear equations was done by GAUSS.
gretl solutions look great but the C matrix results imply as if short-run restrictions are
just superimposed onto the long-run restrictions, leaving the C matrix in your syntax. I
was wondering if the gretl syntax does the above process of solving non-linear
equations.Thank you again,Jay

From your output, it seems that the order of magnitude of variable 4
is
very different from the other four. This could provoke, in principle,
ugly numerical problems.
Could you try what happens if you multiply variables 1, 2, 3 and 5 by 100?
