GPS with PIC microcontroller using MikroC Pro for PIC

Hi guys, I am kinda new to these forums and this is my first question.

I need some help in writing the code to extract NMEA GPS coordinates, display them on a 2 by 16 LCD and send them via GSM for accident alert notification purposes. i have dealt with the GSM part (or at least i think so) but now i need to be able to send the coordinates from the location of the accident occurrence (accident alert system for vehicle project). To do that, i need to extract the coordinates from the $GPGGA line or $GPGLL line (or whichever works best). I need your help guys, I do not have much time left to finish the project. I am using PIC18F45k22 and for simulation of GPS I am using Virtual GPS that i have virtually linked with Proteus (v8.0). I would very much appreciate it if you could help me with a working code that i can integrate into the whole code.

Thanks
