Answer 1

you can do it like this. Not with a groovy variable but can be more dynamic with groovy function/method

def reusableScript(message) {
    sh """
      echo Hello World
      echo Hi ${message}
    """
}
pipeline {
    agent any;
    stages {
        stage('01') {
            steps {
                script {
                    reusableScript("From ${env.STAGE_NAME}")
                }
            }
        }
        stage('02') {
            steps {
                script {
                    reusableScript("From ${env.STAGE_NAME}")
                }
            }
        }
    }
}
