Dear Ox-Users,

I am an absolute beginner to ox-language. I normally use R. Now I am using a program implanted in Ox.

I would like to estimate the same model for 100 different data sets and save the estimates afterwards. Those data sets are saved in file_1.xls to file_100.xls and I would like to save the estimates in results_1.xls to results_100.xls.

Is there a way to do that automatically with a loop? Without having to start the estimation 100 times and replacing the file names per hand? Attached you find some sample code.

I would very much appreciate some help as ox is a closed book for me at the moment.

Cheers,

Katharina
