# llGetStartParameter

*LSL function*

```lsl
integer integer llGetStartParameter();
```

- Returns: `integer`
- Energy: 10

- If the script was loaded with [llRemoteLoadScriptPin](/functions/llRemoteLoadScriptPin/) then that start parameter is returned.
- If the containing object was rezzed by [llRezObjectWithParams](/functions/llRezObjectWithParams/) or [llRezObject](/functions/llRezObject/) or [llRezAtRoot](/functions/llRezAtRoot/) then the return is the [on_rez](/events/on_rez/) parameter.
- If the containing object was manually rezzed, by dragging from inventory, the start parameter is 0.

Returns an [integer](https://wiki.secondlife.com/wiki/integer) that is the script start/rez parameter.

```lsl title="How to use" frame="terminal"
integer result = llGetStartParameter();
```

## Caveats

- The start parameter does not survive region restarts ([SVC-2251](https://jira.secondlife.com/browse/SVC-2251)) or region change ([SVC-3258](https://jira.secondlife.com/browse/SVC-3258), crossing or teleport).
- If the script is reset (using [llResetScript](/functions/llResetScript/) or other means), the start parameter is set to 0.

default
{
    on_rez(integer param)
    {
        llOwnerSay("rezzed with the number " + (string)param);
    }
    state_entry()
    {
        integer i = llGetStartParameter();
        if (i)
        {
            llOwnerSay("I was given the number " + (string)i + " when I was rezzed");
        }
        else
        {
            llOwnerSay("rezzed from inventory (or rezzed/loaded with 0)");
        }
    }
}
```
