A return is a value given when exiting a function or event. The return keyword is used for exiting from functions or events. If a function has a return value, all code paths will need to end in a return statement.

Note: The term "return value" is used when referring to the value retrieved by calling a function.
Also, there is not currently a function to return objects from a land parcel--that's not what this keyword does.

MyGlobalFunction(string str) {
    llSay(0, str);

float WithReturnValue() {
    float    r;

    r = llFrand(10);
    return r;    // also valid: return(r);

default {
    touch_start(integer total_number) {
        if ( llDetectedKey(0) != llGetOwner() ) return; // exit this event if touched by stranger

        MyGlobalFunction("Hooray for SL!"); // call a function without return value

        llSay(0, (string)WithReturnValue()); // call function and use the return value

        WithReturnValue(); // discarding the return value is also legal
