For context Test, the predefined variable value is child_1, while for context Prod it is child_2. When the Job is executed, a text message Specify the Job to run: is displayed.

DEFAULT_CONTEXT: Test,
ContextType {
	NAME: Test
	addContextParameter {
		NAME: child_job,
		TYPE: "id_String",
		VALUE: "child_1",
		PROMPT: "Specify the Job to run:",
		PROMPTNEEDED: true
	}
}
ContextType {
	NAME: Prod
	addContextParameter {
		NAME: child_job,
		TYPE: "id_String",
		VALUE: "child_2",
		PROMPT: "Specify the Job to run:",
		PROMPTNEEDED: true
	}
}
