望大侠指教（程序）

程序如下：
#include<reg51.h>
sbit P10 =0x90;
unsigned char dispbitcode[] ={0xf8,0xf9,0xfa,0xfb,0xfc,0xfd,0xfe,0xff};
unsigned char dispcode[] ={0x8c,0x9e,0xbe,0xfc,0xbe,0x9e,0x8c,0xff};
unsigned char table[10][8]={ 　
{0x00,0x00,0x3e,0x41,0x41,0x41,0x3e,0x00},
{0x00,0x00,0x00,0x00,0x21,0x7f,0x01,0x00},
{0x00,0x00,0x27,0x45,0x45,0x45,0x39,0x00},
{0x00,0x00,0x22,0x49,0x49,0x49,0x36,0x00},
{0x00,0x00,0x0c,0x14,0x24,0x7f,0x04,0x00},
{0x00,0x00,0x72,0x51,0x51,0x51,0x4e,0x00},
{0x00,0x00,0x3e,0x49,0x49,0x49,0x26,0x00},
{0x00,0x00,0x40,0x40,0x40,0x4f,0x70,0x00},
{0x00,0x00,0x36,0x49,0x49,0x49,0x36,0x00},
{0x00,0x00,0x32,0x49,0x49,0x49,0x3e,0x00}
};
unsigned char count,i,scnt;
void delay10ms(void)
{
unsigned char m,n;
for(m=20;m>0;m--)
for(n=248;n>0;n--);
}
void timer0() interrupt 1 using 0
{
TH0 =(65536-4000)/256;
TL0 =(65536-4000)%256;
P2 =dispbitcode[count];
P0 =table[i][count];
count++;
if(count==8)
{count =0;}
scnt++;
if(scnt==250)
{
i++;
if(i==10)
{i =0;}
}
}
void main(void)
{
unsigned char m;
TMOD =0x01;
TH0 =(65536-50000)/256;
TL0 =(65536-50000)%256;
ET0 =1;
EA =1;
while(1)
{
P0 =dispcode[m];
P2 =dispbitcode[m];
if(m==8)
{m =0;}
if(!P10)
{
delay10ms();
if(!P10)
{
TR0 =1;
}
}
}
}
问题是编译时出现 008.C(5): error C100: unprintable character 0xA1 skipped
008.C(5): error C100: unprintable character 0xA1 skipped此错误，应该怎样更改，谢谢了！

P0 =dispcode[m];   中的m没赋值吧？
