Thanks a ton all of you.....
I am now counting the charaters...
when the count reaches max. then i go to next line....

Andy i really didnt understand what you are trying to say....

I've made my own character generater...and thus made my list of pins to be fired and made the functions...
I have written a function called fire...where i give in the pin numbers...and the function fires them for the required ontime...
so for the char 'H'
my funtion is like
H()
{
fire(pin1,pin2,pin3,pin4,pin5,pin6,pin7);
fire(oo,oo,oo,pin4,oo,oo,oo);//oo means pin not fired
fire(oo,oo,oo,pin4,oo,oo,oo);
fire(oo,oo,oo,pin4,oo,oo,oo);
fire(pin1,pin2,pin3,pin4,pin5,pin6,pin7);
}

I really dont get how to go about doing this look up table.
I use a photo interrupter that generates dot pulses and i use them control signal for firing my pins...

Every character is 5 DP long and a space is 3 Dp long...
So all char are equal width..

Also since i am quite new to C also...I have declared all my functions as int
int a();
int b();

is this wrong...
what difference is it if i declare it as char...

Since all char widths are same it would be a whole lot simpler isnt it ?

If my code size gets too long....
should i split up my code and then compile it with sdcc..
If i should split it how do i go about doing it..
Also when my code begins...
should i declare my functions...
what i have done now is...

#include<headerfile>

/*list of functions*/
int timer();
int A();
int B();
.....etc..
int i,j,k;/*list of variables used*/
main()
{
/***************/
}

/********all functions defined*********/
timer()
{
TH....
TL.....
...
..
}

/* this way all functions are defined....*/
Now my doubt is in case if i write
int timer()
{
{
TH....
TL.....
...
..
}

Then is it neccessary to delare the funtion before main() ?
Thats it for now...
thanks again all of you.
