How to Extract Information from the respones of an AT command sent from a PIC

[wa'id]

I'm also having similar issue. In coding my PIC to send an AT command, I wanna extract information (to be used in my code) from the return value of the AT command but i don't what index of the memory where the returned values is stored i will start from.

For instance, if a send

AT+CMGF=1

(1) What will the modem response be?
(2)how will I know the memory index of the receiving buffer at which I can extract my desired information
