Chuck,
NSRange and NSSize are C structures, not Objective-C objects. The ->
operator is the C operator used to access structure fields from a
structure pointer. You can use dot notation if you like:
(*aRange).location = 0;
(*aSize).height = 4.0;
But if you do so you are NOT using the new Objective-C dot notation,
but only the "old" C dot notation.
You should probably take a look at a C reference book to understand
fully.

Tom Wetmore

i think it's used to point to a member of a supplied argument of the

- (void)method:(NSRange *)aRange ofSize:(NSSize *)aSize
{
aRange->location = 0;
aSize->height = 4.0;
}
is it not possible to use dot notation here?
