I might add that certain sets of commands work together in this way, as they are really the same underlying model, done with the same computation. For example,
-probit- and -dprobit-. They run the same computation, but display the results in a different form. You can run either one; then subsequently you can type either one of these commands without arguments to get whichever form of display you want (without having the model redone).

If you type out the full command, then Stata will re-do the analysis.
Replaying results will prove to be much faster than re-estimating the
command, especially when you're working with large datasets or complex
estimation commands.
