:AUTO? Query auto-count
Short-form format: :trig:coun:auto?
Response message: 1 (on) or 0 (off)
With auto-count enabled, the channel count is automatically set to the scan-list-length. For ex-
ample, if there are currently 36 channels in the scan list, then enabling auto-count will set the
channel count to 36. While auto-count is enabled, changing the scan list count will change the
trigger count.
If the scan list is empty, enabling auto-count will set the channel count to 1.
This command is coupled to :TRIGger:COUNt which is used to manually set the channel count.
When :TRIGger:COUNt is used to set the channel count, auto-count will automatically disable.

Line 10 Defines a scan list (channels 1-10 of Slot 1).
Line 20 Enables auto-count, queries the state of auto-count and then queries the channel
count.
Line 30 Addresses the 7001 to talk.
Line 40 Displays the state of auto-count and the channel count (1; 10).
