Yes.
({.~ i:&'/');(4!:4 <'is_unum') { 4!:3''
gives the directory where unum's utils.ijs was loaded from. (And this
can even be done in that same script, after is_unum has been defined.)
That said, for the long run, it would probably be better to stuff this
in a variable and use it where needed, instead of changing the
directory for the entire session. Changing the directory should be
reserved for code that is supposed to take over the session (or, ok,
labs which are intended to teach the user about changing directory).
Thanks,
