First, let's be clear that there is no term "local variable" in Stata. What you are referring to is called a local macro. See also, for example, http://www.stata.com/statalist/archive/2008-08/msg01258.html In terms of your main question, you should pass the value of a local macro to your do-file as an argument; otherwise it follows from the definition of a local macro that the contents of that macro are quite invisible outside the program in which it is defined. foreach x in a b c d { do dummy.do `x' save, replace } If you do this the value of `x' is accessible within dummy.do as `1'. What you need to read is any account of using do files with arguments. What should be fixed in the memory is that "local" means what it says: local macros as such are only visible locally.
