Discussion
L_VIEW shifts the horizontal display area of a list. The horizontal display can change in one of three ways:
- By calling L_VIEW.
- UI Toolkit adjusts the input window display automatically if the user moves to a field that was previously off the screen.
- By sending a D_LLEFT or D_LRIGHT request to the L_PROCESS subroutine.
L_VIEW is only used to shift the contents of the display area to the left or to the right, not to change its size. The display width of a list is fixed once the list is created. If column is less than 1, a column position of 1 will be used. If column is greater than the result of the following equation, the result of the equation will be used instead:
window_width - display_area_width + 1
In other words, the column in which the display area begins is automatically limited to boundaries that do not require changing the display area’s width.
Examples
The following example adjusts the column position of the list whose ID is stored in desc_lst to 20.
xcall l_view(desc_lst, 20)
