Using Light Bulbs with COBOL

Using light bulbs to implement interfaces

You can use the light bulb feature to implement interfaces in managed OO COBOL programs. To use them:

1. Type the definition of the implementing class or value type:

   class-id MyClass implements type Interface

   At this stage the class does not implement the interface and you get an error at its name. Hover the error until the light bulb appears ().

2. Click the light bulb to see the suggested fixes and click the command to implement the interface:

   

   This adds the missing interface members to the implementing class or value type.

Using light bulbs to add the USING directive

When a type is specified without fully qualifying the namespace, use the light bulb feature to add the appropriate USING directive. For example, you want to use System.IO.Path::GetFullPath and you might only have the following defined in the local-storage section:

01 var1 type Path

You get an error message that Path is an unknown type in the Output window, and when you click the line for this declaration, the light bulb icon appears in the margin of the program on this line.

Hover Path until the light bulb appears then click the light bulb icon () to see the suggested fixes. Choose the fix that applies to your code:
