IBM never defined a language called FORTRAN V, or provided a compiler for it, but some of its competitors used the term for their extended versions of FORTRAN. Univac and Data General are two companies that sold compilers for a language which they called FORTRAN V.
In general, FORTRAN V compilers included the CHARACTER data type as a standard feature of the language, and they added the ENCODE and DECODE statements as well. These statements allowed a character variable to be used instead of an input-output device as the source for a formatted read, or the target of a formatted write, and they looked like this:
CHARACTER*80 BUFFER
...
ENCODE(80,11,BUFFER),X,Y,Z
...
DECODE(80,10,BUFFER),P,Q,R
...
STOP
10 FORMAT (3F12.5)
11 FORMAT (3F12.5)
END

I had not heard of Fortran 5 (or Fortran V) and a half-hearted search of the Internet did not find anything.Do you have any pointers to it?Thanks,mdOn Thu, Apr 21, 2022, 18:09 Mike Peckar <mpeckar@gmail.com> wrote:According to the Guiness Book of World records, The computer system that has been in continual operation for the longest period is the Computer Command System (CCS) onboard NASA's Voyager 2 spacecraft. This system has been in continuous operation since the spacecraft's launch on 20 August 1977. Voyager 1's CCS uptime trails it by a couple of weeks and both are still going.Each Voyager has two CCSs, two Flight Data System (FDS) computers and two Attitude and Articulation Control System (AACS) computers, but the FDS & AACS do not operate continuously. The CCS's have two 18-bit word, interrupt type processors with 4096 words each of non-volatile plated wire memory amounting to 69.63 kilobytes. They execute about 81,000 instructions per second and transmit data back to Earth at 160 bits per second. They were originally programmed in Fortran 5.MikeOn Thu, Apr 21, 2022 at 12:32 PM Jon "maddog" Hall <jon.maddog.hall@gmail.com> wrote:Mike,
Believe it or not, both VMS and Digital Unix systems were the same way. They would go months and years without rebooting.
The US Navy had two hospital ships, the "Mercy" and the "Hope". One stationed on the East Coast and one in San Diego. The one on the East Coast used WNT for the servers and the one in San Diego used GNU/Linux. The ship using WNT had to have twice as many servers as the one in San Diego because the Navy rules said that a WNT server HAD to be rebooted every 30 days, whereas there was no such requirement for GNU/Linux. Since a Naval deployment could last longer than 30 days, and since they needed the server services to be up constantly that whole time, they needed twice as many WNT servers.

The HP app I was working with bellied up with memory leaks and I suggested they reboot that server. I was told flat out they don't reboot Solaris servers period. They cleaned up the mess and isolated where in the HP code that the pointer was lost, leaving me the not-so-fun task of filing the bug report with HP.Mike_______________________________________________On Wed, Apr 20, 2022 at 7:39 PM Jon "maddog" Hall via WLUG <wlug@lists.wlug.org> wrote:Tim,
What was the reason for shutting it down?
This reminds me of a story from years ago where a young friend contacted me before a trip to the University of New Hampshire for a Linux LUG meeting.
He asked me if I would go to a particular dorm and knock on the door of what had been his door room. I was to ask if I could unplug the box that was in the corner of the closet in the room. The system had been running for five years in his former dorm room and he had forgotten the login password. He did not want the machine back, just wanted it unplugged.
A young woman answered the door, heard my explanation and let me unplug the machine. "We were afraid to unplug it" she said.
Your machine beat his machine on uptime.
