Did you also try Sergiy's suggestion of using 'aaa' when saving the data instead of 'files'?

I think the file runs well for the first dataset because the variable 'ratio' is created correctly in the first dataset. However, Stata stopped executing for the rest of datasets and I got an error message as follows:
