They occur in a strange order, and some are quite large. If two blocks are allocated, and then the first one is freed, and then a third, larger block is allocated before the second one is freed, some memory is wasted (I fear). What I would like to know is, does DJGPP automatically compact the memory by moving blocks down to fill all the gaps, or do I have to do it manually? How can I do this?
