请编制程序，其功能为：从SOURCE开始的内存区域存放着N个字节的有符号数。现找出最大的数，结果存放到RESULT 指示的，其后存放原N个数逻辑取反后的值。
例如：
数据为：09H，7EH，89H，F6H，17H……67H(N个数据)
结果为：7EH (最大数)，F6H，81H，76H，0CH，E8H……98H(原N个数的逻辑反)
部分程序已经给出，其中原始数据由LOAD过程从文件INPUT1.DAT 中读入从SOURCE开始的内存单元，运算结果要求从RESIULT开始存放，由SAVE 过程保存到OUTPUT1.DAT 文件中。请在BEGIN和END 之间补充使其完整，完成要求的功能。或删除BEGIN和END 之间原有的代码井自行编程来完成要求的功能。
对程序必须进行汇编，并与IO. OBJ 链接产生PROG1. EXE 执行文件，最终产生运行结果。
部分程序如下；
;PROG1. ASM
EXTRN LOAD: FAR，SAVE:FAR
N EQU 30
DSEG SEGMENT
SOURCE DW N DUP ()
RESULT DW N DUP (0)
NAME0 DB ’INPUT1.DAT’,0
NAME1 DB ’OUTPUT1.DAT’,0
DSEG ENDS
SSEG SEGMENT STACK
DB 128 DUP ()
SSEG ENDS
CSEG SEGMENT
ASSUME CS:CSEG,DS:DSEG;SS:SSEG
START PROC FAR
PUSH DS
XOR AX,AX
PUSH AX
MOV AX, DSEG
MOV DS,AX
MOV ES,AX
