routine or stage

[ray.wurlod]

You don't "handle goto" in the Switch stage. You associate an output port number with each candidate value. That's all you have. Anything more complex you're probably going to need a Filter stage or Transformer stage.

Compare that to the heretical action of quoting the entire original post just to add your advice.

All those comparisons can readily be performed in a parallel Transformer stage. Use stage variables to avoid unnecessary repetition of calculations and comparisons.
