Thank you

In Stata, as in much else, subtraction is obtained with minus -.

Thus

gen y = x - z

gives the difference between x and z after which you can -tabulate- y.

Forgive me if I misunderstand your question, but this does appear to be what you are asking.

On the other hand, if this really is what you are asking, it is something you should be able to work out for yourself from the documentation or simple introductions to Stata.
