程序如下：
program ee
...
call sub1(3,SHUZU1,BIANLIANG1,SHUZU2,SHUZU3,SHUZU4)
...
end ee
subroutine sub1()
...
call sub2(3,SHUZU5,BIANLIANG1,SHUZU2,SHUZU3,SHUZU4)
...
...
call sub3(3,SHUZU6,BIANLIANG1,SHUZU2,SHUZU3,SHUZU4)
...
...
call sub4(SHUZU5,SHUZU6,BIANLIANG1)
...
...
call sub3(3,SHUZU6,BIANLIANG1,SHUZU2,SHUZU3,SHUZU4)
...
end
程序调试时出现access violation！在调试时发现程序运行到sub2时，提示BIANLIANG1，SHUZU2,SHUZU3,SHUZU4等变量出现“Undefined address!”但程序都对其进行声明了！不知何故？！
