The word "OK" is display each time SMS is receive using GSM shield problem!!!

hi everyone,
i'm using gsm shield receive sms stored in array code working word ok display each time i'm receiving sms, can please me how solve this.
please refer attachment error i'm encountering.
thanks lot

/*
 sms receiver

 this sketch, arduino gsm shield, waits sms message
 and displays through serial port.

 circuit:
 * gsm shield attached , arduino
 * sim card can receive sms messages

but word ok display each time i'm receiving sms, can please me how solve this.

every time send @ command, response if generated. since process asynchronous, must manage connect response command.

typically, done misusing asynchronous nature of communications, waiting response, doing nothing else until complete response received.

i don't see getting ok response problem solved. of course, if is, unplug device. no ok responses anymore.
