我的一段51液晶程序如下

const unsigned char LED_Tab[]=
{

};
unsigned char LCD_RAM_Tab[sizeof(LED_Tab)];

#define LCD_A 0x01
#define LCD_B 0x02
#define LCD_C 0x04
#define LCD_D 0x08
#define LCD_E 0x10

#define LCD_G 0x40
#define LCD_P 0x80

void HT1621_num_init(void)
{
unsigned char num,LCD_data;

for(num=0; num<sizeof(LED_Tab); num++)
{
LCD_data = 0;
LCD_data = LCD_data | ((unsigned char)((bit)(LED_Tab[num] & LCD_P)) << 7);
LCD_data = LCD_data | ((unsigned char)((bit)(LED_Tab[num] & LCD_E)) << 6);
LCD_data = LCD_data | ((unsigned char)((bit)(LED_Tab[num] & LCD_F)) << 5);
LCD_data = LCD_data | ((unsigned char)((bit)(LED_Tab[num] & LCD_A)) << 4);

LCD_data = LCD_data | ((unsigned char)((bit)(LED_Tab[num] & LCD_D)) << 3);
LCD_data = LCD_data | ((unsigned char)((bit)(LED_Tab[num] & LCD_C)) << 2);
LCD_data = LCD_data | ((unsigned char)((bit)(LED_Tab[num] & LCD_G)) << 1);
LCD_data = LCD_data | ((unsigned char)((bit)(LED_Tab[num] & LCD_B)) << 0);

LCD_RAM_Tab[num] = LCD_data;
}
}

有关键字bit
移植到PIC单片机里，有错误。
LCD.c:350:43: error: use of undeclared identifier 'bit'
请问高手，我该如何修改程序呢？谢谢！
