Thanks for looking into this for me. Trying your suggestions results in the
following:
Yes, all files I try can be opened with the Mac's text edit app and they
look fine. All the files were from before the upgrade and I had used J
extensively to read them without any problems at all.
When I start Jqt it appears to be in /volumes/Macintosh
HD/Applications/j64-807/ and when I try to use fdir to look at contents in
Documents (as you can see below) I don't get anything. So in a way you seem
to be right: Catalina doesn't allow J to read any files not created by J or
certain directories. But this problem is new to me and coincides with
upgrading to Catalina. I have looked at security settings and think I've
given J access to "everything, everywhere". But the problem persists.
Thanks for any help you can provide,
Pablo Landherr
