In the documenation to DB.pm, I read: ##### Global Variables The following "public" global names can be read by clients of this API. Beware that these should be considered "readonly". [snip] $DB::single Single-step flag. Will be true if the API will stop at the next statement. ##### You are trying to assign to $DB::single, which seems to violate the "readonly" stipulation. Moreover, when I hear something described as a "flag", my first impulse is to think of it as a Boolean with 1 usually representing True and 0 representing False. (Granted there is one point in DB.pm where a value of 2 is assigned to $DB::single.) I don't claim to speak definitively here. Thank you very much.
