Section 3: Number and Display Control 33
Windows
The display can be considered a window showing up to eight digits
of the number in the X-register. The X-register—like all registers—
can hold up to 64 binary digits, depending on the word size. What
you normally see is window 0, the eight least significant digits of
the number in the X-register. As you key in more than eight digits,
the most significant digits move off the left end of the display and
into window 1.
Pressing {0 to 7} will display different eight-digit
portions of the word in the X-register. The display returns to
window 0, the eight least significant digits of the word, with each
new entry into the X-register. The highest window number is 7
since the maximum word size is 64. (With smaller word sizes or
smaller numbers, the higher windows will be blank.) Error 1 results
if you specify a window number greater than 7.
Example: The 16-digit hexadecimal value FF00 FF00 FF00 FF00
has a 64-digit binary representation (eight 1’s alternating with
eight 0’s). In Binary mode, you can view the entire number by
executing 0 through 7.

Scrolling
Scrolling with the and keys allows you to move different
parts of a number into the display, one digit at a time. This does not
change the number itself, only what part of the number you see.
The location of the period tells you where to look for the rest of the
number in the X-register. For instance, if the period is on the left of
the base indicator (.b), then there are more digits to the left of the
current display. Pressing [g](>] will scroll the number to the right,
