The crashes occur in ascii2lcd, when it choked on corrupt data, not in the simulation itself. >From this rate I'd conclude that something like 1-2% of events have this problem. Of course, if it happens to be the 2nd event in a file, ascii2lcd will not convert the other 98 events... I did not see this problem with the non-optimized code, at least I don't think so. In any case it was not nearly this bad. --Dave -------------------------------------- David Gerdes, University of Michigan (734) 647-3807 / (734) 936-1817 FAX [log in to unmask] http://umaxp1.physics.lsa.umich.edu/~gerdes/ On Wed, 3 Mar 1999, Richard Dubois wrote: > Hmmm.
