Example

Let's create a file using system routine and windows command prompt:

Creating a file using command prompt
string testfolder="c:/tests"; //assuming that folder `tests` has been already created in c:\ path

system("C:/WINDOWS/system32/cmd.exe /c echo return true; > " + testfolder + "qqq.sil"); // you can run here any other program or custom script 

Let's invoke a windows .bat script file using system routine:

Invoking a windows .bat file
string testfolder="c:/tests/"; //assuming this path exists. 
//we assume in this path a file called `myexec.bat` has been previously created and contains one line `echo Hello;`

//now the following call will return `0.0|[THE_PATH_OF_EXECUTION]>echo Hello; Hello;|`
return system("C:/WINDOWS/system32/cmd.exe /c " + testfolder + "myexec.bat");

For windows operating system, you should put the full (absolute) path of the command.
