I never had to do anything with Time Shared DIBOL on RT-11 thank
goodness; I started out in the DEC world with RSTS/E.

Shouldn't that be "xcall a" and "xcall b" ? :-)

(I've written lots of DIBOL code as well and it's on my CV alongside
all the modern languages I know. One chap at an interview I went to
looked up DIBOL before my interview and commented that it seemed to
be a rather old language. OTOH, I was able to then use it as a
discussion starting point to show I have a good range of experience.)

Yes, this is all starting to bring back some memories. :-)
