Container handling in Dynamic AX 2012

Hi,
static void HandlingContainerJob(Args _args)
{
    container contain;
    int i;
    str containstr;
    ;
    contain = ["DataAt1stPosition","DataAt2ndPosition"]; //Data will be inserted at position 1 and 2
    contain = Conins(contain,3,"DataAt3rdtPosition","DataAt4thPosition"); // from 3rd position onward
    contain = conins(contain,5,"DataAt5thPosition"); // now the data inserted in 5th position
    //or use this technique
 
    info (strFmt("Length of the container: %1", conLen(contain)));
    for (i=1; i <= conLen(contain); i++)
    {
        info (strFmt("container value %1 is %2", i, conPeek(contain, i)));
    }
    //containstr =  con2Str(contain);
    // use to pass from one form to another then again str2con() retrive in container format
    /*
        Condel - Use condel to delete one or more items from a container.
