NF BC Reader Command Reference
You can display one section of a PC-size screen on the reader’s smaller display.
You will only see 16 lines and 20 characters of data at one time. However, you
can use the reader’s display as a viewport to move around and see the entire
screen. By moving the viewport, you use the reader’s virtual display of 25 lines
by 80 characters—the same size as a PC screen.
You can use the viewport movement commands described in this section to
move the viewport in the virtual display.
Note: To use the display as a viewport, you must configure the reader’s display size to
25 x 80. For help, see “Display Setup” in Chapter 12.
Purpose: Moves the viewport down one step in the virtual display, except when it is
already at the bottom line or row. You can set the number of lines the viewport
moves up or down in a single step. For help, see “Viewport Movement Steps”
in Chapter 12.
