Choice Labels

Choose a label from a few known numeric choices.

ChoiceLabels.scala

object Main {
  def main(args: Array[String]): Unit = {
    val code = 
    var label = "other"

    if (code == 1) {
      label = "start"
    }
    if (code == 2) {
      label = "middle"
    }

    println("code=" + code)
    println("label=" + label)
  }
}

  def main(args: Array[String]): Unit = {
    val code = 
    var label = "other"

    if (code == 1) {
      label = "start"
    }
    if (code == 2) {
      label = "middle"
    }

    println("code=" + code)
    println("label=" + label)
  }
}

object Main {
  def main(args: Array[String]): Unit = {
    val code = 
    var label = "other"

    if (code == 1) {
      label = "start"
    }
    if (code == 2) {
      label = "middle"
    }

    println("code=" + code)
    println("label=" + label)
  }
}

choice-labels Control flow can map a small code to a readable label. Simple branches keep the choice explicit and traceable.
