"SS" is the start in hexidecimal.
"EE" is the end in hexidecimal.
There is no space between them.
SS and EE must be in the range 00-0D, specifying the section of a block cursor with 00 being at the top and 0D being at the bottom. For example, to obtain a cursor of the lower half of a full block cursor, specify 080D.
BR ensures that the ending value is no less than the starting value. If it is, it interprets the ending value as equal to the starting value.
