Rob, how about this:
You could ship Euphoria with the user defined type "string". In contrast
to suggestions that had been made in the past concerning a "string"
type, this would not mean any change of Euphoria's internal affairs
during normal operation. People use a user defined "string" type anyway,
and when using "without type check", there is no loss of speed.
The advantage would be that in case of a crash, Euphoria knows what
constants and variables are strings, and can display them accordingly.

Bernie:
Until there will be a better solution, you can use my contributiuon
<http://www.rapideuphoria.com/errconv.zip>. It makes it possible for
an Eu 2.5 program to convert its own "ex.err" file after a crash.
