The bugs are yours.
Thank you!
In your second bug, you are not executing 1&Z: . You should have @: not &: .
Does &: not work because of this? https://code.jsoftware.com/wiki/Vocabulary/ampco The monadic use of &: is deprecated. Use @: instead. Some compounds of the form f&:g are not recognized for special code in places where f@:g is recognized, if only the monadic form of the compounds is eligible for special treatment.
