# Example: lr_get_attrib_long

In the following example, lr_get_attrib_long retrieves the value of the loop parameter from the mdrv command line string that was used to run the script:

    test1   -host sun2   -loop 4   -time 10

where test1 is the name of the executable, and host, loop and time are command line options. lr_get_attrib_long assigns the value to a variable, iterations. This variable is incorporated into the script and sets how many loops to perform.

    Action() {
        long loop;
        int i;
        iterations=lr_get_attrib_long("loop");
        if (iterations==0){
            lr_error_message("Illegal value \n");
            return;
        }
        for (i=0; i <iterations; ++i) {
             /* perform test operations... */
        }
    }
