Re: st: -generate- and run time contingencies
Nick Cox had a slightly shorter version, eliminating the creation of
the OK variable.
I am reminded again that it would be nice if the -replace- command
somehow left behind the number of changes it makes (which it
displays, but does not leave for a program to pick up.) It's been
discussed before on statalist I think, and making -replace- r-class
would likely break all kinds of programs, but still it would be handy
to be able to get to that somehow....

I think you've got a winner. I tried it with a 1,000 cases and then
100,000, and it went pretty quickly. Then, I tried it with
10,000,000 cases - it took a few minutes but it finally got it done.
