实现PIC用户区内任意段的数字排序，并将最大的数字和最大的数字所在的存储单元保存

在这里假设没有相同的存储单元

比较简单，但是我想对于我来说，让我进一步了解pic汇编指令-PIC users realize arbitrary region of the figure above to sort, and the largest figure and figure where the biggest memory cell preservation　assumption here is not the same memory cell is relatively simple, but I think for me, let me further know pic compilation Directive
