Tim,
If you look at pp 65-69 of ,
you will see the published definitions for Fortran H.

Yep. The model 2671 paper tape reader along with the 2822 controller.

in FORTRAN the card punch is unit 7
Ah yes - that sounds familiar - thanks Tim!
I wouldn't have a clue about the paper tape reader
I was thinking it might be 2 if there is such a convention - memories
are hazy...
I think all of those low numbers initially had a conventional assignment.

I think VS FORTRAN has or had a customisable upper unit number limit.
Applications would crash off if they tried to use a unit number higher
than was configured. We just used to make it 99, IIRC.
Yes VS Fortran did have a customisable upper unit number. I found that out
when the systems guys put in a new version of VS Fortran, and one of our
programs promptly aborted with an invalid unit number message, or something
like that. I just looked at some of my old JCL members (which I copied to a
CD before the mainframe was decommissioned where I used to work) and in one
of the FORTRAN ones I made a comment that you needed to specify UNTABLE=99
in the VSFORTL macro (not that I really know what that means..).
Ever since that occasion, the first thing I did when they put in a new
version of VS Fortran was to run a small test program that used unit number
80! (I can't remember why I didn't use 99 - perhaps 80 was the highest unit
number we used).
Cheers,
Greg
