you can unlock it by restarting your computer... however its like array's and memblocks really
if you don't make sure you wipe them when you exit DarkBasic Pro then they'll stay resident within the memory.
its a pitty it isn't possible to put a nestling error on the Lock & Unlock commands as they will just open up these data sections to the whole computer and cause memory leaks if not used properly ... so i'd suggest you use them with a little caution

One block follows the suit ... the whole suit of blocks is the path ... what have you found?
