Well, I think that nothing will append anything to anything else within the program, if no memory has been requested from the OS to append to its local pool. And when the program closes, what do you think should specifically happen to anything _within_ the program that affects anything still noticable? When the program closes down, it ceases to interact with its environment, and so it may do whatever the programmer deemed useful or neccessary, without any external effect. > This to try to understand why with fpc, for big project like compiling fpc > him-self, the memory used do not stop to increase and the speed of > compilation decrease. I cannot see what relevance your question has to this. Memory "used" by the program as reported by an OS function does _not_ in any way relate to anything happening _within_ the program - specifically it does not relate to the degree of internal use of the allocated memory. You might gain access to that only through the use of debugging or reporting functions built into the program itself, i.e. by "instrumenting" the program accordingly. If you're wondering whether fpcs (internal? external?) use of memory does not increase and the speed of compilation does not decrease, then this might - will - be due to careful memory management and thoughtful code optimization. After all, it depends the least on anything going on when it's done with its task an closing down to finally exit. -- -- (Weitergabe von Adressdaten, Telefonnummern u.ä. ohne Zustimmung nicht gestattet, ebenso Zusendung von Werbung oder ähnlichem) ----------------------------------------------------------- Mit freundlichen Grüßen, S.
