Hi folks.

Doing a manual for the electronics in a military vehicle and came upon this:

Bild stapeln AUS/EIN

The document is describing the data formats used for various commands, so this is just one bit in a word. No other context is available except that this is associated with a periscope in the vehicle.

Now I have seen the Kudoz with all sorts of stacking and piling. None of that seems applicable here.

Could it be "cascade" as in MS Excel? When you have two spreadsheets open, if you click on Window -> Arrange and then pick Cascade, it gives you both spreadsheets, one behind the other and offset by a little so you can easily switch between the two.

Does this make sense?

All contributions gratefully accepted.

Thanks.

Yours,
