Try this: append the path to file_search_maxima, then call file_search
to return the path for the data file.


file_search_maxima : cons ("/my/path/###", file_search_maxima);
file_search ("my.data");
 => /my/path/my.data
read_list (file_search ("my.data"));
 => (stuff)

In the search path, "###" matches any file name.

Incidentally with /my/path in the search path, batch("foo.mac")
and load("foo.mac") automatically search /my/path for foo.mac.
