Arduino's serial communication with gsm board - geolocation

Question

I am trying to write a program where arduino receives text from the gsm module.But my program is able to read the first text and perform a duty,but i want it to receive multiple texts and perform individual tasks for each respective texts?Any help will be great.Thank You.
#include <SoftwareSerial.h>
SoftwareSerial gsm(2, 3);
String inString[64]; // string to hold input coming from device
String read;
int count = 0;
boolean verifyingDone = false; // flags to determine the action completed and to perform next action
boolean regist = false;
boolean registercomplete = false;
boolean location = false;
void setup()
{
// put your setup code here, to run once:
Serial.begin(9600);
gsm.begin(4800);
delay(100);
gsm.print("ate0\r"); // removes the echo from the device
delay(100);
gsm.print("at+cnmi=1,2,0,0,0\r"); // to receive a text
Serial.print("The Device has been Intiated");
}
void loop() {
if (gsm.available())
{
while (gsm.available())
{
read = gsm.readString();
verifyNum(); // verifying the number
/* verifyingDone=true;
if(verifyingDone){
delay(1000);
gsm.print("at+cgpsinfo\r");
delay(1000);
checkGps();
verifyingDone=false;

Thank You,Above code is justa tryout ,any help is welcome!
