I am a bit astonished to read advices like this. What kind of 
development tool is it that needs such kinds of precautions to debug a 
program correctly? What else has the programmer to consider? Do I need 
years of knowledge about the internals of Free Pascal/Lazarus to use it? 
I feel put back some decades in software develpement.
