Variable expansion in Jenkins Pipeline

I am trying to expand a variable in a Jenkinsfile. I first concatenate a couple of strings to create this variable and would like for it to be expanded so that it is interpreted as my environment variable.

I am looking for something like the exclamation mark ! in bash. 

pipeline {
    agent: any
    environment:{
        CRED_DEV_PROJ = "my_credentials"
    }
    stages {
    stage("my_stage"){
        steps{
            script{
                LST = [
                    ["DEV", "PROJ"],
                    ... some more lists ...
                for (def i= 0; i < LST.size(); i++) {
                    CRED = "CRED_" + LST[i][0] + "_" + LST[i][1]
                    sshagent (credentials: [CRED]) {

                        ... do stuff ...          

                    }
                }
            }
        }
    }
}

The variable CRED should be expanded so that it leads to my_credentials, so that the line sshagent (credentials: [CRED]) is executed correctly.

That should be env.“${CRED}“.
