AH = 48h BX = number of paragraphs to allocate
Return:
CF clear if successful AX = segment of allocated block CF set on error AX = error code (07h,08h) (see #01680 at AH=59h/BX=0000h) BX = size of largest available block
Notes: DOS 2.1-6.0 coalesces free blocks while scanning for a block to allocate. .COM programs are initially allocated the largest available memory block, and should free some memory with AH=49h before attempting any allocations. Under the FlashTek X-32 DOS extender, EBX contains a protected-mode near pointer to the allocated block on a successful return
