Maintaining Launches
A launch defines the Natural Development Server (NDV) on which a Natural application is executed, as well as the user, session parameters, and code page that are used. All launch configurations are stored in the launch.json file in the workspace's .vscode folder.
You can maintain a launch in the following ways:

In the Natural Properties Manager, by choosing
maintain launches in the
Connection group of the
Environment panel, which is also where the project's launch is selected. See also
The Natural Properties Manager.

In the
Run and Debug view of Visual Studio Code, which uses the same
launch.json file.
Adapt the launch to your specific requirements. You can also duplicate the launch to create configurations for different environments, for example NatDebugLinux for debugging on Linux and NatDebugMainframe for debugging on mainframes, together with the corresponding attach counterparts NatAttachLinux and NatAttachMainframe.
The following launch configuration types are provided:
Note:
The parameters which are marked as Do not modify in the following sections are required by the Natural debug adapter and must not be changed.
