I've been compiling and running some Fortran programs on my
microPDP11/53 computer and have questions about Fortran VIRTUAL arrays.
Details: KDJ11-D/S cpu with 0.5 MB of ram, additional 1MB of Qbus ram.?
I'm running RT11 V5.7 ZM and using the F77XM compiler, version 5 (I think).
What I am seeing is that when I use VIRTUAL arrays instead of the usual
memory below 64K the run times are dramatically slower.? Is this normal?
Could it be something else?? The other memory board?

I was assisting an older client the other day, a former Yale prof,
and he's been programming since the late 1950s.
He knew people who worked at Bletchley Park. He also mentioned he
knew people who had manually scribed their programs on some sort of metal
cylinder. Which computer system was that?
Part of what he'd like me to help with is a circa 2001 Compaq / DIGITAL
version of a FORTRAN programming environment. He had not yet found
the installation media so we could try to get it running on Windows 10.
I wonder if it will...

Could this be something that uses the same technology as a drum program
card on a keypunch?

Probably not.

Music Box? Could he be confusing something with BOMBE set up?

Do you mean DIGITAL/Compaq FORTRAN for Windows? Or something older such as VAX Fortran
which had many extensions.

Yes, it was under Windows. What do you know about it?
I find these tips:

I suspect the installer is 16 bit and won't run on 64-bit windows. It's also
not available as a free download.
If he hasn't kept the media I suspect he may be at a dead end. Its costly
licenced software which is well protected by its owners...

I used Digital Visual FORTRAN quite a bit in the 90's.? I still have the
installation CDs for v. 6.0A Professional Edition Intel version from
December, 1998.? It featured most VAX extensions, I think.? But at the
time, my main research machine was a Sun with twin 200MHz Ultrasparcs.?
I wish I could have kept it.

I must have lost the thread--what does this have to do with inscribing
metal cylinders for programming a system of the 1950s?
Color me puzzled.
