Summary: Programmer's extender a big disappointment

I purchased programmer's extender (Invention Software), both volumes I and 
II, to help me develope a relatively simple application. After spending
several frustrating days tracting down bugs in Invention Software's code, I
decided that I would have been better off without it. There were several
bugs, some of which would not allow procedures to work at all, others 
would cause data loss to the user of your program. One by one I abandoned
their code and wrote my own procedures. (In that sense, it's a good 
learning environment!) They don't give you all of the sources, so I
wa lucky that the bugs didn't show up in compiled code (although they
may yet). Now my app is about 5% Invention's code, and if I ever do
a major rewrite, I will purge all of it out.
