Now fixed for the next release. Thank you for finding and reporting this error. To get around the crash for the nonce, you can use laminate=: ,: instead of ,: .
By the way, your second expression will give a result rather than signal a length error. It is not possible to get a length error from ,: . ----- Original Message ----- From: Ian Shannon <[email protected]> Date: Wednesday, July 29, 2009 2:27 Subject: [Jgeneral] J crash To: "[email protected]" <[email protected]> > Hi there, > > Notification of a system crash. > > J602 on win XP SP2. > > > ========= > NB.
