It does seem a bit quirky, though, to use whitespace in this way. I wasn't really aware of this oddity in the design of warn(). I guess it makes sense, somehow. It makes more sense, though, to just provide some context iformation, then get the more specific error or warning message ctained in the variable. Whatever the particular features that come and go with the choice of whitespace, it makes more sense to explicitly call for the information provided in $!. > > > Fact: This is the original question of this thread and what most of > the replies address.

Nice point. Now back to business. You get a lot more information back by asking for information.
