Hi David,
Can you explain why this is false or how I have this wrong? Steve said device
but he really meant to say virtual device. The antonym of ATTACH is DETACH but
strangely DETACH has many antonyms (e.g. ATTACH, DEFINE CONSOLE, DEFINE GRAF,
...). If you detach a console, then the antonym is define console. If you
detach a real address, then the antonym is attach. As for "require", I think
this is what you are talking about being false. I should have been clearer and
said the opposite of detach console is define console (not attach console).

AFAIK, (since VM R6.0) this statement has never been true.
