Can I open a program on my Computer using mbed LPC11U24?

Hello community! Can someone please help me? I thought, why not letting my mbed LPC11U24 open a program on my Computer... Is it possible?? if yes, how? I thought of a standart Void Function

Function

#include "mbed.h"

DigitalOut myled(LED1);
DigitalOut myled2(LED2);
InterruptIn btn_1(P1_16);

void start() {
//here Comes the command       
}

int main() {
    myled = 1;
    btn_1.rise(&start); 
    while(1) {
       myled2 =! myled2;
    }
}

Edit

Can I do it this way? But there is an error...

Error: Undefined symbol system (referred from main.cpp.LPC11U24.o).

Starting File

#include "mbed.h"
#include <stdlib.h>

DigitalOut myled(LED1);
DigitalOut myled2(LED2);
InterruptIn btn_1(P1_16);

using namespace std; 

void start() {
          system("F:\\Text.txt");
       myled =! myled;
}

int main() {
    myled = 1;
    btn_1.rise(&start); 
    while(1) {
       myled2 =! myled2;
    }
}

Hi,

You got an error, because you don't have a definition of the system() function.

If you want to open a file in mbed local storage, you can use LocalFileSystem rather than system() function. Please refer following link for more detail.

http://developer.mbed.org/handbook/LocalFileSystem

Please note that the LocalFileSystem works only mbed LPC1768 and LPC11U24.
