From that I do not understand what you did. What do you mean by "went
to use it"? How did you make the isv files?

Also, what is about string arrays that makes you call them not
regular?

file_which always returns a string scalar, which is why the indexes
you use (123,123) do not exist. It is just the path for the first file
found matching the conditions of its arguments.
