  Interrupt:   21h     Function:   58h
 
  Title:       Get or Set Allocation Strategy [Version 3.0+]
 
  See also:    Allocate Memory Block
 
  Description:
 
     Obtains or changes the code indicating the current MS-DOS strategy
     for allocating memory blocks.
 
     Input                           Output
 
     If getting strategy code        If function successful
       AH = 58h                        Carry flag: clear
       AL = 00h                      And if called with AL = 00h
                                       AX = Allocation chosen
     If setting strategy code               00h = First fit
       AH = 58h                             01h = Best fit
       AL = 01h                             02h = Last fit
       BX = Desired strategy code    If function unsuccessful
            00h = First fit            Carry flag: set
            01h = Best fit             AX = Error code (01h)
            02h = Last fit             See: ◄Error codes►
