Hello！
When I use stata to clean data,I always want to keep track of every step I take so that I can use backup file to get every dta which is produced during this period until I get the data that can be used to analyse. Dofile is a good choice,but there are so many steps that you don't need to write a sentence,such as changing a number or dropping a observation,especially when there are so many steps like this and there are no rules to put them together.I feel confused when there are so many files to process and they are chaotic.Do I need to record every step when cleaning data? Is there a better solution to backup files ?
