Carved in mystic runes upon the very living rock, the last words of
Dikkie Dik of comp.lang.php make plain:

I'm not sure I follow you here. I'm trying to get value names *from* a
string, and then get the values for those names.

For some values, yes. But in other cases, such as error reporting, I need
to access an actual variable.
Anyway, I have it worked out now. But thank you for answering.
