Delete an unreachable program implementation

When you create a program, it contains the forward declaration and the implementation. The forward declaration contains the

extern

keyword, such as

extern program myProgram()[];

If you delete the forward declaration without deleting the implementation, you receive the error

Unable to resolve the reference to the Program 'programFQN'. Error code: DS0038.

You must delete the implementation file to resolve this error.

To delete an unreachable program implementation

Open the Code Editor from the program element by right clicking the element and selecting

Code Editor

In the Code Editor, navigate to the line number and Character column of the error message, then select the program implementation that you want to delete.

Select

to the left of the component to open the Code Actions menu.

Select Delete unreachable program implementation
