To display the contents of this section, you must click
the Add Screen element button or select a Screen
call line in the tree. If you add a Screen call, you are requested
to select a Screen among those already present in the current location,
or define a new one. In this section, you must give the characteristics
of the Screen call
Calling a Screen enables you to integrate the description
of an already existing Screen into the current Screen.
This enables
you to manage the fixed fields of the various Screen maps in the Dialog,
such as the information displayed on the Screen top and bottom categories.
Note: If
the called Screen contains a called Screen itself, this last call
is ignored in the first level call.
- Screen
- This is the called Screen. Note that you can change
it by clicking the Change... button.
Position
- Position type
- In this field, you specify the positioning of the Screen element:
- Relative positioning
The specified line
and column numbers correspond to a move from the Data Element located
just before in the list. The calculation of the positioning from
the preceding Data Element is of two types, according to the nature
of this field:
- Data Element call (for an elementary or repeated Data Element,
whatever its presentation): The starting point of the positioning
is calculated from the top right-hand corner of the contents (and
not the label) of the previous Data Element.
- Screen calls: The positioning is calculated from the lower right-hand
corner of the called Screen in the calling Screen.
- A: Absolute positioning: In this case,
the line and column numbers correspond to the absolute address of
the element on the Screen.
Notes on position: The position
defined by the position type, the line and column numbers is that
of the first character of the:
- Contents if the presentation type is: Data Element only, or Data
Element with a column label.
- label otherwise.
- Line
- In this field, you specify, on two numeric characters, the line
number which determines the position of the element
- In a relative positioning, this is the number of lines between
two elements. If the presentation type corresponds to a column heading,
the number of lines in the column heading is automatically added,
upon generation, to the indicated number.
- In an absolute positioning, this is the line number on the Screen.
Line overflow is automatically controlled.
If both the
line and column numbers equal zero, the element is automatically positioned
on the next tabulation point available.
- Column
- In this field, you specify, on three numeric characters, the column
number which determines the position of the element:
- In a relative positioning, if the line number is zero, the column
number corresponds to the number of spaces between two elements on
the same line. If the line number is greater than zero, the column
number corresponds to an absolute positioning.
- In an absolute positioning, the column number is the address of
the element on the line. A zero value corresponds by default to column
2 upon generation (column 1 being reserved for the attribute). If
the value is 1, the attribute is on the preceding line.
Any line length overflow and field overlapping are automatically
detected. However, the presence of a space in front of each field
is not verified.
If both the line and column numbers equal zero,
the element is automatically positioned on the next tabulation point
available.
