Placeholder
This property specifies a short hint that describes the expected value of an input field. The short hint is displayed in the input field before the user enters a value. It doesn't affect Drop-List combo-boxes.
The color of the placeholder text can be configured by setting iscobol.gui.placeholder_color in the configuration.
Note - The placeholder text is not necessarily displayed in the same position as the input text.
 
Example - Define a combo-box with a placeholder text
screen section.
