Dear Statalisters, I have the following dummies gen dummy1 = 1 if nearesthospital ==1 gen dummy2 = 1 if nearesthospital ==2 gen dummy3 = 1 if nearesthospital ==3 gen dummy4 = 1 if nearesthospital ==4 gen dummy5 = 1 if nearesthospital ==5 Etc. etc. The number of dummies that have to be generated are up to 40 or more. I was thus thinking of creating a local macro for generating the dummies and avoiding typing the commands every single time. I read the macro section on the Stata User's Guide, but unfortunately cannot see how to apply the explanations to the above-mentioned case. Any idea?
