I was interested in writing some assembly code for the lego mindstorm, I don't plan on writing an incredibly complex program though. I am learning asm for the z80 chip so I have a little experience. I only want a single threaded application with one (...) (21 years ago, 16-Jul-03, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)

When the system or a user program requests memory (new in C++ or malloc/calloc in C) the memory is taken from this block (from mm_start to the end of memory) What might be confusing is how the (...)
