Re: Extracting information from PL_exception()

Great, thanks for the assist, Carlo. Actually, your reply made me realize I
had barely been leveraging the power of the PlTerm classes.

One thing in the online documentation I don't quite understand, though:

"Additionally, \cfuncref{PL_exception}{0} returns the pending exception in
the current query or 0 if no exception is pending. This can be used to
check the error status after a failing call to, e.g., one of the
unification functions."

Is there messed-up formatting there, or is that intended to be
readable/verbatim syntax?
