Steve,
You need to add an @ in the declare to tell it the string argument is passed by reference. Also the second argument tells the api how big the buffer is:
BOOL GetUserName(
LPTSTR lpBuffer, // address of name buffer
LPDWORD nSize // address of size of name buffer
);
declare GetUserName in win32api string @ sBuffer, integer @ nSize
UserName = space(25)
nSize = len( UserName )
GetUserName( @UserName, @nSize )
