Sorry, but I find it difficult to believe that what you report is
exactly right. It is contrary to the logic of Stata.

What I can believe is that a local macro defined in a do-file is not
visible outside it.

That is precisely what -local- means. Local macros are not visible
outside the locale in which they are defined, meaning precisely one of

1. a -program- so defined
2. a do file
3. do-file editor contents
4. interactive session.

You need to use a global macro if you want a macro to make sense
outside the do-file in which it is defined.
