I do not know why this happens. The relevant code here appears to be run1_jlab_ which uses 0!:111
But 0!:111 'x=:2',LF,'y=:3',LF,'x+y',LF,'u+v',LF does not give the value error, while run1_jlab_ 'x=:2',LF,'y=:3',LF,'x+y',LF,'u+v',LF does give the value error. Maybe it has something to do with the locale? This might be a bug in the interpreter?
