However, allow me to give you a few tips: your script is very difficult to debug. You're computing the orthogonality condition on one monster line. I _suspect_ something goes wrong at some point with the parentheses or with the sheer size of the line, and that's what makes gretl crash (which, I repeat, is a bug --- internal message: something appears to go wrong in real_append_line() in lib7src/monte_carlo.c). In general, though, it's advisable to break down a complex statement into a series of smaller ones; often, this also makes your script more efficient, since you avoid recomputing thet same quantities several times. See the attached script, which is a slightly revised version of yours. Please note that my script runs, but may be wrong in more than one place: what you're trying to do is not very clear to me, so I may have misunderstood your code. However, I think my version is much easier to debug. Oh, and another thing: gretl isn't matlab. You don't need semi-colons at line endings :-) Riccardo (Jack) Lucchetti Dipartimento di Economia Università Politecnica delle Marche r.lucchetti(a)univpm.it http://www.econ.univpm.it/lucchetti

Allin, Thank you for the quick response and efficient process. I'm so used to application crashing under Windows, I didn't bother with bug report before and worked around when possible. Working with a fixed version within 12 hours is so much easier.

The bug was due to mis-handling of the maximum command line length in the context of loops. This is now fixed in CVS and the Windows snapshot. But I agree with Jack's advice that the script would be more efficient with the very long gmm line broken into manageable pieces.
