Suppose we create dummy variables from ids1 to ids50 by writing
tab industry, gen(ids) ,
how can I include 50 dummies in the model instead of writing
reg y x ids1 ids2 ids3 ... ids50 ?
Thanks in advance.
I usually do it like this:

reg y x ids*

So long as you don't have other variables, besides the dummies, with that kind of prefix (ids--), then regress y onto all fifty dummies, as well as x.
