Specifying Ranges When you specify a range of lines with a command, you must always give
the range as lower/higher. EDIT searches the line numbers sequentially
from the lowest line number to the highest; it isn't able to move randomly
in the file. For example:
*LIST 17/13
-- ERROR --
ALL RANGES MUST BE GIVEN AS LOWER/HIGHER
Simply retype the command, listing the range of lines in the correct order.
