While this is a minor inconvenience, what I find annoying, sometimes, is the fact that an array has to have at least one element. This can cause serious problems in some cases. For instance, SELECT ... INTO ARRAY won't create the array if you happen to select zero records. Work-around: check for _tally. Problems arise when you aren't aware of this situation.

Note: I have no experience with Clipper.
