Hi Jack, I see three 'pro' files: profback.sas7bcat, profile.sas7bcat, profile2.sas7bcat. The first two have dates of Aug 14, and the third has a date of June 10, all 2020. August 14, a Friday, was the last time before the win10 upgrade that I used sas. The June 10 date was probably the first time I used sas on 'my' machine. I see two 'reg' files: register.sas7bdat dated Jan 26, 2018, which must be a provided data file, and regstry.sas7bitm dated Aug 25, 2020. I did what you recommended and now have a history. Thank you. I'd like to ask a follow-up question. How do I go about editing or changing the defaults? I know there is Tools->Options but the range of options there seem to be miniscule but bear in mind that my reference is the edit->options tabs in spss, of which I am a very long time user, where many things are adjustable. Here are trivial things for sas: open program shows the last used directory, the output window is not opened at startup, the not-enhanced editor window is not opened at startup. Thanks, Gene Maguin
