Variable values are assigned and inspected using the EDASET and EDAINSPECT method calls.
Inspecting variable values provides the application with the ability to customize its behavior in a manner suitable for the environment in which it is running. This enables the application to make use of functionality when it is available, without causing errors when it is not available. Setting a variable enables the application to customize behavior in a manner appropriate to its requirements.
EDASET and EDAINSPECT parameter values are always expressed as numeric codes.
EDASET checks the setting value combination for validity before processing. When an error is detected, the API sets the status parameter to an appropriate error status code and returns that status code.
