And I agree, too!
O'Storage_Units
makes a lot more sense than
O'Size / System.Storage_Unit
Why not just save me the trouble, and make 'Storage_Units a predefined
language attribute?
I'd actually go further and make
O'Bytes
a predefined language attribute, which the compiler is free to reject if
Storage_Unit /= 8 on this machine.
I'm always a little nervous when I'm making an OS call that explicitly
calls for length in bytes, yet I have to express the length in terms of
Storage_Units. I know that thinking in terms Storage_Units is more
portable, but there's nothing portable about
Starlet.QIO (
...
P1 => O'Address,
P2 => O'Size / System.Storage_Unit,
...
QIO wants bytes, so why not let me say that directly?
