so the read/write (data transfer)  element is numbered zero

which says to my silly mind, more the tape in element 1 to element 0.

Why is it complaining about a 2 -> 1 move
when it should be doing a 1 -> 0 move?

If you do a load 0 does it do the desired 1 -> 0 move?

Doesn't make sense, but if this was in a shell script
I was debugging I would be looking at an off by one
type error.  Maybe one part of the system uses 0 base
and another uses 1 base.  But I can't see it happening
when using mtx directly.
