Hi,
Here, I’ve changed the previous code using “array of strings”.

xdata unsigned char string[20][21]  =  {"1.rotor rpm",
					"2.generator rpm",
					"3.manual yaw cw",
					"4.manual yaw count cw",
					"5.auto yaw cw",
					"6.auto yaw count cw",
					"7.start",
					"8.manual stop",
					"9.vibration error",
					"10.hyd pump error",
					"11.brake error",
					"12.brake solenoid",
					"13.gear oil motor on",
					"14.hydraulic motor on",
					"15.gear motor off",
					"16.hyd motor off"};
void program(void)
{
	lcd_writecommand(SET_RAM_0);
	lcd_clrscr();
	screen=0;		//to enter the digit password

	pass_status=enterpassword(menu2.password);

	if(pass_status)
	{
	screen=1;
	lcd_clrscr();
	lcd_gotoxy(0,0);

		for(i=0;i<16;i++)
		{
		lcd(&string[i]);
		lcd_putc('\n');
		}
	}
	return;
}

Sure, I’ll implement using table driven structure …the constraint is, under each option in the main menu, there are about 25 to 30 parameter options to be displayed. So, guide me in the scrolling function.

i’e., how to change the display start line during execution of the up/down scroll keys.

thank you for guiding me.

regards,
veena.
