Temporary hide number when dialling from dialpad

I know you can use
Allow: *30#[SEND]
Prevent: #30#[SEND]
but these are permanent unless you make the changes again.
I want to hide my number for just the one call.
What is the GSM code to do it?
Using a Palm Treo to dial if it makes any difference.
(Can it be done on any GSM phone?)
Thanks

anyone is interested.

#31#nnnnnnn <SEND> withholds
*31#nnnnnnn <SEND> reveals if you default to withhold
