If you have such a function, you can use lcd_puts() or lcd_printf() to display a complete string.
A tip that you can try here is to add :
#device PASS_STRINGS = IN_RAM
in your code to force string constants to be copy in RAM.

I think what you are asking is how to display more than 16 characters per line on a 2x16 character LCD? This type of display will store 40 chars per line but can only display 16 chars at any one time.
The answer is simple, you cause the LCD to shift-left multiple times to display the "hidden" characters.
If you have a "send_byte" routine in your LCD library, use the following code snipppet to shift the LCD text to the left.
//send instruction to LCD for text to shift left
//this will allow more than 16 chars per line to be displayed
lcd_send_byte(0,0x18);
