Thanks to Bill for sharing the setplot routine.
Another way to store the system variables is to write them to a save file:
save,/sys
and then recall them later:
restore
In this manner, you can recall the state from another device. This method is
an alternative to the one used in Bill's setplot. It avoids having to know all
the names of the system variables. You can restore system variables for your
favorite devices from files using the filename keyword. It is slower, and
avoids a common block (not a big deal). I'd call it an alternative to Bill's
method.
