Sorry, Rich. I guess I gave an example which was too simplified. I
actually figured out a different way of doing it because I realized I had an
ID variable which, in our example, looks like:
ID x y z
- - - -
1 A A
1 A A
1 A B A
1 A B A
1 B B
1 B B
Then I was able to replace 'z' with 'x' by using -by ID-. I suppose there
were too many cases to give just one good example of my question, but
luckily I figured out a way to answer it myself. Thanks for the response,
nonetheless. Much appreciated.

Subject: Re: st: simple replace
I'm a little confused; why not just go -replace z="A"- if you really want
'z'
to be all "A"s?
