Sorry if this is considered expected behaviour that should be caught by a user supplied exception handler but typing product [1 .. 100] /1.0 causes hugs98 to crash with Win98 complaining of invalid page fault. I presume the use of mixed math with / is the problem? but I would expect the error to be handled more gracefully (as typing product [ 1 .. 100 ] % 1.0 is) Regards Nigel Brown
