SCROLL
The SCROLL statement specifies vertical movement of displayed values in all or
some of the fields of a screen array within the current form.
lines is a literal integer, or the name of a variable containing an integer value,
that specifies how far (in lines) to scroll the display.
Here lines is a positive integer, no greater than the number of lines in the
screen array, indicating how many lines to move the displayed values vertically
in the specified fields of a screen array. If you omit the BY lines
specification, the default value is one ( 1 ) line.
Specify UP to scroll the data towards the top of the form, or DOWN to scroll
toward the bottom of the form.
