Subject: how to control to save plots to which dev
In-Reply-To: <4E3C1414.3090304@gmail.com>
Yes, but I thought the parameter to dev.set() should only be the value
returned by dev.next()/dev.prev(). So I read the help page again. It's a
little embarrassing - I missed the sentence "Devices are associated
with ... a number in the range 1 to 63". I should have read the help
page more carefully. Thanks.
