Yes you're exactly right Sergiy! And I use "aaa" just for illustration purposes, but your advice is definitely well taken! Thank you so much!

Zhan, you probably need save `"`aaa'"', replace. And perhaps something better than "aaa", perhaps "oneFile" for readability. Best, Sergiy Radyakin

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:
