我写了个程序用伟福e6000仿真的时候编译出错，说“程序超出地址范围”。我改了好几次都还是这样，往高人指点一下，谢谢了。源程序如下：
#include <REG2051.H>
#define uchar unsigned char
sbit vol_tran=P3^0; //电压14V档和28V档转换
sbit cor_14 =P3^1; //14V调节
sbit cor_28 =P3^2; //28V调节
sbit dec_f =P3^5; //F端电压探测
sbit led =P1^0;
//---------------------延时函数-------------------------
void delay(uchar xms)
{
uchar i,j;
for(i=xms;i>0;i--)
for(j=110;j>0;j--){;}
}
//---------------------主函数-------------------------
void main(void)
{
while(1)
{
vol_tran=0; //待机14V档
cor_14 =0; //14V档高电压：16V
delay(50);
if(dec_f==0) //判断调节器为14V系列
{
cor_14=1; //14V档低电压：13V
delay(10); //延时1毫秒
if(dec_f==1) //判断调节器是否导通
cor_14=0;
delay(10); //14V档高电压：16V
if(dec_f==0)
cor_14=1;
delay(10); //延时1毫秒
}
else //28V系列
{
vol_tran=1; //电压跳到28V系列
cor_28=0; //28V档高电压：30V
delay(10); //延时1毫秒
if(dec_f==0)
cor_28=1; //28V档低电压：26V
delay(10);
if(dec_f==1)
cor_28=0;
delay(10);
}
}
}
