测试反义词(例如，看某物是否不是复制的):
<pre>
    if (!(PERM_COPY & llGetInventoryPermMask(myitem, MASK_OWNER)))
        llSay(PUBLIC_CHANNEL, "/me [" + myitem + "]: owner doesn't have copy perms.");
</pre>
提醒下一位业主在出售前设置哪些权限，选择哪些权限需要设置;
<pre>
CheckPerms()
{        
    string item = llGetScriptName();
    integer nextOwnerPerms = llGetInventoryPermMask(item, MASK_NEXT);
 
    if(PERM_COPY & nextOwnerPerms)
        llOwnerSay("Set no copy");
 
    if(PERM_MODIFY & nextOwnerPerms)
        llOwnerSay("Set no mod");
 
    if(PERM_TRANSFER & nextOwnerPerms)
        llOwnerSay("Set no transfer");
}
 
default
{
    on_rez(integer start_param)
    {
        llResetScript();
    }
 
    state_entry()
    {
        if(llGetOwner() != llGetInventoryCreator(llGetScriptName()))
            CheckPerms();
    }
}
