    Still having problems to reproduce this:
    
          ⌹,
      0.5
            ⌹2
      0.5
    
    Does it also happen in a CLEAR WS ?

    fixed.

    Actually you need INTERRUPT (= double ^C within short time) and not
    ATTENTION (= single ^C).

    fixed. I should mention that some invariants in the IBM APL2
    language reference
    manual are incorrect (at least my PC APL2 differs from the manual).
    The
    
          (0≠L)/R   ←→    ⊃,/L⊂R on page 188
    
    seems to hold only if L⊂R is not empty.
