Michael,

Thanks for the advice, but could you just clarify what you mean b
'return value'?
I tried a shorter password of 12345chr(13)67890 and it took 2.48 t
unlock it. And the fact that I can unlock it by entering the passwor
again suggests that I'm not doing it right as you say it can't b
undone.

thanks for your help....again!

regards
