Seasons greetings to all.
I've been lurking on the list for a while and not really involved in
vintage computing at all over the past year or so.
What I will say is that I am in the process of trying to organise another
DEC Legacy Event for 2018 - it will either be in May or November, to be
decided shortly.
To bring my post on topic I can recommend the 'Writing VAX/VMS Applications
using Pascal' by Theo De Klerk if you want an introduction into some of the
VAX/VMS specific features such as ASTs.
I don't have a technical background with DECnet, only as a user. It does
indeed work great. I'm jealous I wasn't involved in DEC itself - Steve
Davidson has some great stories about the scalability of VAX/VMS hardware
and networking infrastructure.
Regards, Mark.

A SYS$QIO is just a system call used to perform I/O.
An AST is an ?asynchronous system trap?, otherwise known as an interrupt
routine.
An event flag is a process synchronisation mechanism.

My experience with OpenVMS was mostly doing SYS$QIOs, ASTs and Event Flags

I don't know what SYS$QIOs, ASTs or Event Flags are yet, but controlling
factory shop floor equipment sounds like my cup of tea!
Setting up anonymous file access sounds straightforward. I need to read up
on access control for launching remote batch jobs.
