Difference between STATA 12 and STATA14

[NOURHENE BEN YOUSSEF]

Hi everyone,
I am currently using STATA 12 and I am considering upgrading to STATA 14. However, I am worried if my existing codes will work or not with the new STATA version.
Thanks.

Usually, but not always, if you preface your code with

version 12

it will continue to work the way it did in version 12. Depending on the code it may not be necessary to do that, but sometimes it is. Stata is quite good about maintaining backward compatibility.

Nourhene:
my experience is that older Stata codes (I surmise that you mean .do and .dta files) will work on a more recent release.
Obviously, the opposite doesn't hold.

Thanks Richard & Carlo!
