初学汇编 一个小程序 有逻辑错误，，，，哪位帮下忙~~

从一组20个数中找出正数和负数，存起来，并显示正负数的个数

DATAP DB 20 DUP (0) ；用来存正数

显示结果不正确，一执行就dos就死了

[songkai2008]

NEGETIVE1:CMP [SI+COUNT],0H
JG NEGETIVE1
改成NEGETIVE1:CMP [SI+COUNT],0H
JG NEGETIVE2
后
存的正负数正确 但是显示的正负数个数不对

结果显示 20，0 现在问题变成如何比较带符号数了 估计是都按大于0算了，，，，，

CMP [SI+COUNT],0H 有问题，COUNT取得是偏移地址是固定不变的，[SI+COUNT]则取得永远都是同一个地址的值，即ds:[COUNT]处的值，即控制循环的值
