INT 21 - DOS 2+ - ALLOCATE MEMORY
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 AH=59h)
BX = size of largest available block
Notes:  DOS 2.1-5.0 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
