Jeff,
I vote for bug. Though it could be it's 2 different errors as far as 4D is
concerned with a compiler error tripping first which doesn't show up
interpreted.
I've noticed -1 being returned as an error code for a really wide range of
errors. Or, it's a case like this where the compiler trips before the
actual coding error does. It makes it harder to figure out nonetheless.
