Nice.  I looked at fixing RT11 RTS applications like MACRO, but that's not possible because the RT11 date format stops in the early 21st century (5 bit year field).  Perhaps RT-11 has created a solution, but if so I don't know it.

I was thinking of posting the *.diff files, that way if someone has the sources, the fixed version can be created.  FWIW, there are in fact V10.1 sources on the net, on Bitsavers for example.  But I'm as reluctant as you are to post full sources myself.

Given that this stuff is in Github, I guess you could put your changes in a fork and generate a pull request.  Or send me the files if you don't want to go through that.

I had not heard of that and I have not seen it, or any Mentec materials for that matter.
