Okay, there's $currentPassage, but is there also a $previousPassage?

  You need to state which Story Format (both name and version) you are using when you ask a question, as answers can be different for each one.
  
  I am unsure which story format you are asking this question about because after using code similar to the following to do a quick test story for all the ones currently available for Twine 2 (including SugarCube 2 and Harlowe 2) I was not able to find one that had a built-in $currentPassage variable.

  currentPassage: $currentPassage

  Oh yes indeed! Sorry, that was Twine 2 and Harlowe. I found a $currentPassage used in a test story on these forums and I downloaded it, it seems to work fine on Harlowe. Thank you for your answer.

  Did the test story include either a header or footer tagged passage that contained code like the following:

  (set: $currentPassage to (passage:)'s name)
  

  ... because Harlowe does not have a built-in variable named $currentPassage.
  
  
  You can implement your own $currentPassage and $previousPassage variables by:
  
  1. Placing code like the following in a header tagged passage.

  (set: $previousPassage to $currentPassage)
  (set: $currentPassage to (passage:)'s name)
  

  2. Placing code like the following in a startup tagger passage:

  (set: $currentPassage to "")
