If I redim an array at runtime, will it free the memory of the old array of the same name??

I would think so, although it's possible Blitz might wait until the program ends. You could try a test program that does a lot of redimming and watch the memory usage. Edit: I just tried this and the WinXP task manager showed memory usage going up and down slightly as the program did Dim a( Rand( 5000, 15000 ) ) a hundred times.

OK, so I take it that it does free the mem. I agree its not the best thing in the world to do and I usually avoid it, but it seems a good idea when I load a new tile map (2d array) ocassionally. Ta very much Tric!! :)
