[DUG]: Dummy Q of the week

[Alistair George]

I have forgotten; can someone remind me:
I have a component in unit1, where a relevant call is:
IceLock.GetHDSerialNumber;

I need to make the same call in unit2.
The following is not right:

implementation {in unit2}
uses unit1;
{$R *.DFM}

And, yes, I have read the help!
thanks,
Al+
