Although this list setting will usually work, the properties of a record
aren't really guaranteed to be in any particular order. It would be safer
to use:

set {text_returned, button_pressed} to the result's {text returned,
button returned}

or, faster:

set {text returned:text_returned, button returned:button_pressed} to
the result

I don't know if it still works in Panther, but the fast hack for ensuring
plain text in Jaguar is:

try
set text_returned to <<class ktxt>> of (text_returned as record)
end try

("<<" and ">>" are the characters produced by pressing option-\ and
shift-option-\ on English-language keyboards.)

Ah. Remember the days when this could all be done in one line? :-(
