Problem saving the IP address for later use.

PICO shimmed to ESP8266.
I use wifi.getIP() and print the resulting IP address, then assign it to a global variable.
Printing the global variable MyIP doesn’t work.
Later typing MyIP; into the left pane I get the IP address.
So what’s going on and is there a solution?

//MyIP.js
//26Sep 2016
//espruino board with ESP8266
//PICO  with ESP8266
//var Hardware=0; //Espruino board
var Hardware =1; //PICO
var SSID="ssis";
var key= "routerpw";
var Serial;
var MyIP="";
function test(){
if(Hardware===1)Serial=Serial2;
if(Hardware===0)Serial=Serial4;
if(Hardware===1){
 digitalWrite(B9,1); // enable on Pico Shim V2
 Serial.setup(115200, { rx: A3, tx : A2 }); //Pico
}
if(Hardware===0)Serial.setup(115200, { rx: C11, tx : C10 }); 
//espruino board
console.log("Start connection process");
var wifi = require("ESP8266WiFi_0v25").connect(Serial, function(err) {
  if (err)return 1;// throw err;
console.log("Reset the ESP8266");
  wifi.reset(function(err) {
    if (err)return 1;// throw err;
    console.log("Connecting to WiFi");
    wifi.connect(SSID,key, function(err) {
      if (err)return 1;//throw err;
      wifi.getIP(function(l,ip){console.log("IP= ",ip,"\n\r"+l);MyIP=ip;});
      console.log("Wi-Fi Connected");
      console.log("MyIP= ",MyIP,"XXX");
      console.log("MyIP= "+MyIP+"XXX");
// Now you can do something, 
 var server = require("net").createServer(function(c) {
  // A new client as connected
  c.write("Hello");
  c.on('data', function(data) {
    console.log(">"+JSON.stringify(data));
  });
  c.end();
});
server.listen(1234);
    });
  });
});
}//end test
var x;
console.log("Start");
x=test();
if(x!==0)console.log("Try again");//error seen
if(x===0) console.log("Exit Seen");

The output:

>echo(0);
Start
Start connection process
Try again
=undefined
Reset the ESP8266
Connecting to WiFi
Wi-Fi Connected
MyIP=   XXX
MyIP= XXX
IP=  192.168.1.3
null
>MyIP;
="192.168.1.3"
