As far as I can see, $info is not modified at all in the above code.

    I'm sorry, I see what you're getting at now.

    No, I don't *directly* modify the variable ... however I let the *underlying* Tk system modify it. In the optionmenu call I set the -variable option to a reference to $info, and that allows $info->{subdir} to be updated as the selection in the optionmenu (a drop down list) is made ... and I'm pretty sure this works. In the error message the string that it reported matched exactly with the one I selected in the optionmenu.

    Sorry this has taken up so much space.
