Yes Joe, you are correct EDX was the OS

Was a long, long, long time ago.

I worked with a great programmer that used to call it "beasty" and was the
type of person if given a challenge she would rock up at work in comfy
clothes, a large bag of snacks and proceed to work all day and all night to
achieve the goal.

And when you said you like to do "CLEAVER THINGS" it reminded me of her and
how you could patch the Control Program Support (CPS) if you wanted/needed
to do something that was not supported.

For fun I just googled this and found a really interesting snippet ...

Series/1 still in use as part of U.S. nuclear weapon command and control
systems

In May 2016 the United States Government Accountability Office released a
document that covered the need to upgrade or replace legacy computer
systems within Federal Agencies. According to this document, there is still
a Series/1 that "Coordinates the operational functions of the United
States’ nuclear forces, such as intercontinental ballistic missiles,
nuclear bombers, and tanker support aircraft." This system still uses
8-inch floppy disks, however the agency plans to update some of the
technology by the end of the 2017 fiscal year.[1]

I wonder if it got decommissioned???


Cheers

Actually, technically the language was EDL; the operating system was EDX
(Event Driven eXecutive).

What I remember was that the language actually ENCOURAGED runtime
modification of the program code.  As just one example, you could label
a GOTO instruction and then modify the target of that GOTO with the
address of another instruction.

I was 18 or 19, and way too clever, so I made use of this sort of
trickery the time.

( And those of you who know me, know my opinion of "clever"
programming.  :P  )

While I working with RPG on a S34 I also worked with EDX on a Series1.

Anyone remember EDX ?

IBM Australia use to use Series1's to control their door security back in
the 70's - Funny story of how to make doors open with a metal bottle
opener :-)
