SELECTION-SCREEN ULINE [[/][pos](len)] [MODIF ID modid]
[ldb_additions].
1. ... [/][pos](len)
2. ... MODIF ID modid
This statement creates a horizontal line on the current selection screen. If you do not make a formatting specification [/][pos](len), the system creates a new line across the width of the selection screen beneath the lines already filled. The maximum length of this line is 83.
The additions ldb_additions can only be used in a selection include for a
logical database.
... [/][pos](len)
The formatting specification [/][pos](len) is used to position the line on the selection screen. len specifies the length of the line and pos the column from which it is drawn. If several elements are displayed in one line, you can omit this specification and the line will be drawn starting from the current item. If an oblique symbol (/) is entered, you must specify a length and the system draws the line on a new row; otherwise, it is drawn on the current row. If several elements are displayed in a line, you can omit the oblique (/). If there are conflicts with existing screen elements, the system will be unable to generate the selection screen.
You must specify the length len directly as a positive number with a maximum of two digits. If a line is too long, it will be cut off outside
blocks with frames at position 83 and at the right edge
of the block inside a block with a frame. You can either specify a number between 1 and 83 for
pos or one of the expressions pos_low or
pos_high. The expression pos_low specifies the position in which the input field for a parameter or the first input field for a
selection criterion is to be
displayed. The expression pos_high specifies the position
in which the second input field for a selection criterion is to be displayed. If the statement is part
of a block with a frame, the system interprets a number specified for pos to determine the position of the frame.
... MODIF ID modid
The addition MODIF ID assigns the line to the
modification group
modid, which is assigned to column group1 in
the system table screen. This means it can be modified
using a MODIFY SCREEN statement before the selection screen is displayed.
