In terms of security, this approach is a problem. You can do almost anything from that point.

DoCmd("DO my.prg") 

will work too. Instantiate classes? Open forms? Mimic existing stuff into something new? You have full control from that point. See what you can do in terms of compiling and creating at run time. That's huge.

Never ever do that.
And don't argue nobody knows your structure. This is named security through obscurity.
