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 controlling factory shop-floor equipment

 

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.
