I might add that it is important to know that _rc is set only for a command that occurs under
-capture-.

If you want to see the output of the command AND subsequently test _rc, then do...
capture noisily ...

Yes. I don't think you need [P] to understand _rc.

gets you started. _rc is usually zero, whenever
a command works -- to Stata's satisfaction. If
you see a message like

unrecognized command:  rgeress
r(199);

r(199) is _rc of 199 in another guise.
