I am runing a regression analisys with Interaction terms:
reg y i.x#c.z
now i d like run a test for the this interaction in differents categories.

You have a categorical by continuous interaction which tells you
whether the slope of y on z differs among levels of x. The easiest
way of looking at this is
. margina x, dydx(z)
You have only one categorical and one continuous variable so I'm not
sure what you mean when you say, "I d like run a test for the this
interaction in differents categories."
