Depending on their function, input/output fields look differently. The corresponding flags are to be set for this in the Screen Painter (see Technical Notes).

The display of the input fields depends on the respective platform and uses the system resources provided for this purpose.

Input fields are displayed three-dimensionally, recessed in the surface of the template.

Input fields are displayed two-dimensionally and have an L-shaped border.

Input/output fields have the color of the platform-specific system resources.

The color of the 3D shadow or the 2D border depends on the system resources; if no resources are available, black is used.

The length of an input field should indicate how many characters the user can enter. The length of a field thus automatically corresponds to the maximum number of characters the user can enter.

For input data, the system standard is a non-proportional character set (equidistant script) which is required to indicate the length specification.

Output fields are usually displayed in proportional typeface.

Required fields are flagged by a question mark "?".

Fields in which an error has occurred are highlighted by a different background color.

If input fields cannot be changed in a particular dialog situation, the input field has the color of the window background. The three-dimensional display of the input field does not change in the process.
