Int 21 Fn 4A - DOS 2+ - Resize Memory Block [D]
AH = 4Ah
BX = new size in paragraphs
ES = segment of block to resize
Return: CF clear if successful
CF set on error
AX = error code (07h,08h,09h) (see AH=59h)
BX = maximum paragraphs available for specified memory block
Notes: under DOS 2.1-6.0, if there is insufficient memory to expand the block
as much as requested, the block will be made as large as possible
DOS 2.1-6.0 coalesces any free blocks immediately following the block
to be resized
