The "Data List Editor" is a list of binary values with a maximum length of 2
31
bits.
This value corresponds to a file size of approx. 268 Mbyte.
To increase readability, the bits are displayed in groups of four. The current cursor
position, the length of the list and the list filename are displayed above the list. The
offset starts with the value 0 which corresponds to the bit position on the left side of
the first row, i.e. the beginning of the list. On the left edge of the editor, the last
three offset positions are specified at the beginning of the row.
An existing list can be edited in the insert or replace mode.
SCPI command:

The buttons below the binary list simplify the editing.
