学习高德纳，先用铅笔在纸上写出算法好像真是不错的注意～; e10_2.asm assume cs:code,ss:stackstack segment db 16 dup (0) stack endscode segment start: mov ax,stack mov ss,ax mov sp,16 mov ax,1000h mov dx,10h

1.显示字符串assume cs:code,ds:data,ss:stack data segment db 'Welcome to masm!',0 data endsstack segment dw 16 dup (0) stack endscode segment start: mov ax,data mov ds,ax mov ax,stack

jcxz跳转后，紧随其后的代码不会执行，要特别注意出栈入栈是否匹配; e10_3.asm assume cs:code,ss:stack,ds:datadata segment db 16 dup (0) data endsstack segment db 64 dup (0) stack endscode segment start: mov ax,stack

将以0结尾的字符串中的小写字母转变为大写字母; Name: letterc ; Function: Converts character c in the string end with 0 to its uppercase equivalent if c is a lowercase letter and has an uppercase equivalent ; Parameter:ds:si
