How to use an edited ado file without restarting Stata session?

[Minchul Park]

I am editing my ado file.
Whenever I make some change, I want to check whether the edited ado file works in the way I intended.
However, Stata seems to use the unchanged ado file even after I save the edited ado file.
So, I am restarting Stata whenever I want to check the edited version, then it works well.
But, you know, it is really hassle task to restart Stata very frequently.

How can I use the edited ado file without restarting Stata session?

That is done by using the command:

discard

* Consult the help file:
h discard
* in which you can read:   Use discard to debug ado-files.

ericmelse Thank you so much, I can save much time!

-discard- is a nuclear option, isn't it? See also -program program_name drop- or -capture program program_name drop-

[daniel klein]

Stephen meant to say

program drop program_name

discard might get rid of more than you want, but I think in terms of developing and certifying ados, it is usually what you want.

As an aside,

capture program drop program_name

often appears inside ado-files. It is completely useless there. If there really was a program with the same name in memory, the ado-file -- including the line capture program drop ... -- would not be executed in the first place.

On Daniel's first point: yes, he read my mind. (thanks)

Stephen Jenkins daniel klein I understood the point. Because I have only one ado file, I had no problem so far. But, as you mentioned, program drop seems more efficient and what I exactly want. Thank you guys so much.
