[Jprogramming] introducing j plus plus (jpp) - follow-up

['Pascal Jasmin' via Programming]

I don't get this error.  Though, I've been slow to fix a bug related to multiline definitions that do not have a blank line following them.

Further, if now in the same jqt session to use menu command Tools > Package Manager, I get error:

  | runpacman_jpacman_ 0
  |file name error: script
  | 0!:0 y[4!:55<'y'
  |value error: runpacman_jpacman_
  | runpacman_jpacman_ 0

What’s wrong?
