Thank you for the relpies. i am glad to know that the level set has been released. It seens that my host site has not yet implemented the level set (based entirely on the performance which I see), but that is not unusual as it does everything by committee and a decision on this or that can take nine or more months. I will prod the LISTSERV adminstrator about it. If there was a note on this list about release of the latest level set I beg pardon, I overlooked it. If there was no note, there should have been. Thank you for the replies. I will now belabor the host site administrator about it. He will tell me it is the committee's decision, not his, whether to implement the level set or not. I will believe that it is installed when I see perfomance matching the LSOFT claims for the level set. I have not yet seen such, which is why I asked, knowing that the host site tends to be quite slow about installing new versions of whatever. Douglas Winship [log in to unmask]
