PCA$HELP.HLB  —  SCROLL
    PCA Command

    Scrolls a display's screen window in a specified direction over
    the text of the display, making additional display contents
    visible.

    Format

      SCROLL  [display-name]

1  –  Parameters 

 display-name

    Specifies the screen display to scroll. This display must be a
    predefined display (PLOT, SRC or OUT) or a display established
    with the SET DISPLAY command. If you omit this parameter, the
    current scrolling display, as specified by the SELECT/SCROLL
    command, is scrolled.

2  –  Description 

    The SCROLL command is used to view display contents that are not
    currently visible in a display's screen window. Using the SCROLL
    command, you can move the screen window up or down over the text
    of the display. You can also move it left or right. By scrolling,
    you can see all parts of a large display, even though only a
    small part may fit in the display's window at any one time.

    The easiest way to use the SCROLL command is to use the
    predefined scrolling keys (see the Keypad entry in PCA HELP for
    PCA key definitions).
