The reason for missing the 2nd and 4th lines are (my opinion) the 20x4 LCD adress ranges are different.

like this :

0,1,2...........17,18,19
64,65,.........81,82,83
20,21,.........37,38,39
84,85,.....101,102,103

After writing to position 19, you must jumpt0 64th position, so u need to command the LCD
to reposition to 64 and after writing to position 83 , u need to jump to 20th position.

So u can make a function for this... Hope i am not wrong

you're right firoz.. Alvanbert needs to write a function that takes care of printing string and wrapping them to new line when they reaches the end of first line or say 20 characters.

u can take 4 varialbles as LINE1 , LINE2, LINE3 and LINE4 and save ur message in them with 20 charactes each.
supose ur sms is in SMS_INFO character:

for(int i=0;i<20;i++)
    LINE1[i]=SMS_INFO[i];

for(int i=0,j=20;i<20;i++,j++)
    LINE2[i]=SMS_INFO[j];

for(int i=0,j=40;i<20;i++,j++)
    LINE3[i]=SMS_INFO[j];

for(int i=0,j=60;i<20;i++,j++)
    LINE4[i]=SMS_INFO[j];


then u can write a small routine that wil send all 4 variables to 4 lines.

LCD_4line(){
LCD_Add(0x00);
for(int i=0;i<20;i++)
      LCD_data(LINE1[i]);

LCD_Add(0x64);
for(int i=0;i<20;i++)
      LCD_data(LINE2[i]);

LCD_Add(0x20);
for(int i=0;i<20;i++)
      LCD_data(LINE3[i]);

LCD_Add(0x84);
for(int i=0;i<20;i++)
      LCD_data(LINE4[i]);
}

If i were to write , then i would do something as this. May be there are easy ways, but am not sure

Y do i write codes in long ways

hehe this is moe simple
LCD_4line()
{
LCD_Add(0x00);
for(int i=0;i<20;i++)
      LCD_data(SMS_info[i]);

LCD_Add(0x64);
for(int i=20;i<40;i++)
      LCD_data(SMS_info[i]);

LCD_Add(0x20);
for(int i=40;i<60;i++)
      LCD_data(SMS_info[i]);

LCD_Add(0x84);
for(int i=60;i<80;i++)
      LCD_data(SMS_info[i]);
}


Some one Give proper way here , else i might spam here with all sorts of stupid coding of mine

Thanks Alot firoz3321, your code worked just fine for me. Now i can display the whole message on the four lcd lines.

i however still have some issues. I would love the message to start from the last point on the last line and then scroll from down upwards both horizontally to the left and upwards with each word following each other. Is it possible.

Secondly, can someone write me a function to delete sms from sim memory after a specified period of time(e.g After 5 Hours). THANK YOU ALL FOR BEING HELPFUL.

@ Alvanbert
first step is to extract relevant message from sms
after that u has to check first # then display whole message till the 2nd #
i think when u extract message from sms
that will be ur real message that u want to display
i think no need of two #
