请教个汇编语言问题，各位高手帮帮忙解答下，万分感谢。
y=-1，程序如下; x&lt，y=1 :CODE,1
JMP STOPNEPB;0:STACKSTART,XX
MOV YY:DATA,AX
MOV SS,0STOP:
MOV AH:MOV AX; x=0;0，程序我觉得只要定义数据段就可以了,SS?)TOP
LABEL WORDSTACK
ENDSDATA SEGMENTXX
DB YDATA ENDSCODE SEGMENT
ASSUME CS,0
MOV YY;y=0，Y放在YY单元,4CH
INT 21HCODE
SRART我的主要问题是程序里头有分别获取堆栈段的地址给SS，当x&gt,TOP
MOV AL：STACK SEGMENT STACK
256(，前前后后我也没见用到什么堆栈:
MOV YY,DS,AX
MOV AX题目是问设计一个分程序,DATA
MOV DS。设X放在XX单元,0FFH
JMP STOPNEPA,栈订指针地址送给SP的代码，为什么程序里还要定义256个字的堆
提问者采纳
没有用到。估计是考虑=没有堆栈编译时会被WARNING，还有可能是这个程序原来是其他程序的子程序，挪过来的时候没有进行移除。你可以去掉

是没有用到。
调用子程序、执行终端都需要用到堆栈，以便执行完成后返回到正确的代码段

当前位置：
一个java web项目，客户追加了一些功能(v4.0)，在原来的环境中老版本（v3.0）还要运行，新版本和旧版本的发布目录是平行的。
以下是生产环境的一些信息： ------------------------------------------------------ Using CATALINA_BASE:&& /xxx/apache-tomcat-5.5.33 Using CATALINA_HOME:&& /xxx/apache-tomcat-5.5.33 Using CATALINA_TMPDIR: /xxx/apache-tomcat-5.5.33/temp Using JRE_HOME:&&&&&&& /xxx/jdk1.5.0_20 Using CLASSPATH:&&&&&& /xxx/apache-tomcat-5.5.33/bin/bootstrap.jar Server version: Apache Tomcat/5.5.33 Server built:&& Feb 8 :31 Server number:& 5.5.33.0 OS Name:&&&&&&& Linux OS Version:&&&& 2.6.32-279.el6.i686 Architecture:&& i386 JVM Version:&&& 1.5.0_20-b02 JVM Vendor:&&&& Sun Microsystems Inc. -------------------------------------------------
旧版本系统路径：/xxx/stastt3/WebContent 新版本系统路径：/xxx/stastt/WebContent 新旧版本的系统里面的文件目录结构都是完全一样的，新版本只是追加了一点功能。
/xxx/apache-tomcat-5.5.33/conf/Catalina/localhost下有2个配置文件： 1.stastt.xml &?xml version=&1.0& encoding=&UTF-8&?& &Context &&& docBase=&/xxx/stastt/WebContent& &&& reloadable=&true& &&& workDir=&/xxx/stastt/WebContent/WEB-INF/classes&&

---------------问题补充---------------
：忘记说一句，之前的项目是用Eclipse JUNO export war的，现在用的是LUNA export war的，不过项目的jre依赖都是1.5，不会是IDE升级后编译出问题了吧？我看了看编译设置compiler compliance level是1.5。
