The Elements of a DCO-Script

Constants

5.4Constants

Constants are place holders and based on the data types described in the Section 5.2, "The DCO data types and their value ranges".

Constants always remain the same throughout a project. They can be used any number of times at any place within the project and their values can easily be edited at a central level in the OScAR-Pro Customized Operator.

When using a Constant in the subsequent course of the DCO-script, its name is output between

%%characters. In the subsequent execution of the DCO-script, the Constant is automatically substituted in the script with its assigned values.

Example

You can, for example, define a specific color for a specific type of Button as a Constant and subsequently assign this Constant as text color to other Buttons. If you want to change the color of the Buttons of this type later, you do not need to edit each of these Buttons individually but can change the color of the Constant centrally, instead.

5.4.1The attributes of Constants

Constants can have the following attributes:
