1) Do you a full copy test environment?
2) How many libraries are involved?
3) How large is your production environment?
4) Have you identified all the objects that need recompile?
We done this process many times, I have some utilities I've created to simplify the process.

always stored in the program object.

I understand this situation very well, because we have objects here that we either don't know for sure that the source matches, or even in a few cases no source at all. So I'm not taking his predicament lightly at all.

But listening to the schemes being bandied about to get around this, I think it's better to bite the bullet now and just recompile. Most likely, the source does correspond to the live executable; but even if it doesn't, the added cost of fixing/testing the errant programs (which I fully appreciate could be very high) is probably going to be worth it in the medium to long term.

I'm guessing that the programmer actually would be glad to do the work, as long as he has the full support of his higher-ups. (That is, if his higher-ups can be made to understand and appreciate the value of doing it right, and give him the proper latitude to do so.) I know, this is also a luxury that not all programmers have.
