If I’m following all this correctly, it seems your criticism is that R doesn’t
provide a run-time function that is equivalent to a compile-time macro. You do
realize that __FILE__ is not part of the C programming language - it’s a
predefined variable recognized by the cpp - the C preprocessor program.
Similarly, SAS_EXECFILENAME is a predefined variable that can be recognized by
the SAS macro processor, but has no meaning in the SAS language itself.
So, to go back to your original post:

This is what a macro processor does. Are you asking for a macro language in R?
