Declaring (initializing) array without size

Hi!

I'm having some problems declearing an array. I am trying to make an array that contains messages that I will later display on an LCD display. I am using a 2D char array, but I don't want to specify a fixed size to the second dimension. At the moment i am doing this:

const char message[][20] = {
	"RS232 Monitor",
	"By: Oyvind Tjervaag",
	"V1.0",
};

The problem with this is that a lot of space is wasted scince there is only one string that fills up the 20 chars. Here the "V1.0" string will be the 4 chars I want to use followed by 16 0x00...

The annoying thing about this is that I have have done it before.. But I can't find the code where I did it...

I thought I could do it like this:

const char message[][] = {...}

But that is just giving me the error, "Too many initializers" , which of course means that I am trying to add more variables than what can fit into the array.

Could someone give me any hints about this?

Thanks
Øyvind

Is this what you ended up with?
(This works fine for me.)

void LCD_String (char ROW, char COL, char *string)
{
	GoToXY (ROW, COL);
	while (*string)
		LCDdata (*string++);
}



char lcdstr[] = "LCD Ready";
LCD_String(1,1,lcdstr);
