I have a tiny system with no external memory. What I've learned from the monitor map file (mon-int-sio0.m51) there are a couple of gaps. As I'm running out of memory with my application, how could I link it so that every byte the monitor is not using would be available for me? The only thing I've done so far is locate XDATA to 11d0h and CODE at 1200h. I must comment out tested functions to be able to add new ones now. Thanks, Harri
