Help graphics for subprogram calls
With help graphics you illustrate the call parameters of subprograms.
The Steuerung places the help graphics to the left next to the dialog
box of the subprogram call.
If you append an underscore "_" and the input field name in capital
letters (beginning with L) to the name of the file, a separate graphic
will be displayed for that input field. If no separate help graphic exists
for an input field, the graphic for the subprogram will be displayed (if
available). By default, the help window is displayed only if there is a
graphic for the subprogram. Even if you want to use individual graphics
for the address letters, you should define a graphic for the
subprogram.
Graphic format:
 BMP, PNG, JPG images
 Size 440x320 pixels
You integrate help graphics for subprogram calls as follows:
 The subprogram name, entry field name and the appropriate
extension (BMP, PNG, JPG) must be used as file name for the help
graphic.
 Transfer the help graphic to the directory: \nc_prog\Pictures
