calling GetTickCount():kernel32.dll?

[Mike Eggleston <mikee@xxxxxxxxxxxxxx>]

I have the code:

DefineDLLFunc: "kernel32.dll", long, "GetTickCount", long;

vars: tickcount(0);

tickcount = gettickcount(0);

print("d=", date, " t=", time, " tc=", tickcount);

but it gets an error within TS6. How do I easily call this function?
I know the function returns a DWORD, but when I define the function
above as using a DWORD instead of a long it also fails.
