memory leaks?

Blitz3D Forums/Blitz3D Programming/memory leaks?

Right. I know that, but what about while it is running, and between levals? How do I know that everything was removed that should have bin?
An example of this would be a screensaver I made a while back. I made it into an executable and left it running for 11 hours. Then when I came back to it, it was moveing very slow. And when I tried to exit it, my computer froze up. My guess is it froze up while trying to free up everything on exit, but I don't know.
So if I have a game and it is is not corectly deleting types
and data, It will get slower and slower with each leval.
What I am asking is a way to track Types instances,Data index,and asosiated variables like x#=entityx#(player\ship), where x# is the asosiated variable.
And if I have say dim(1000) and say it refers to enemy ships, each ship gets deleted when hit by a player bullet and again at the end of the leval. But how do I know for sure that all the data was deleted.
