I'd not have thought so.  Whatever strange thing was happening it 
stopped with your last code suggestion.  I suppose I should try to 
figure out what was going on.  But it only happened with the environment 
viewer. Must have been evaling the output, but somehow to new values tho 
it sure didn't look like it.  In the program after four runs:

    ...
    │ -=5679ENVXgiks │
    │ -=5679ENVXgiks │
    │ -=5679ENVXgiks │
    │ A=/aArchive │
    │ A=/aArchive │
    │ A=/aArchive │
    │ A=/aArchive │
    │ aa=/tmp/tmp_to_env.t9 │
    │ aa=/tmp/tmp_to_env.t9 │
    │ aa=/tmp/tmp_to_env.t9 │
    │ aa=/tmp/tmp_to_env.t9
    ...

Then seeing what's going on:

    $ set | grep "aArchive"

    A=/aArchive
    A=/aArchive
    A=/aArchive
    A=/aArchive
    A=/aArchive

... so God knows ...
Some invisible difference? Some non-printing char that's significant, 
but invisible? But it's not a problem any more.

Here's what the output of " typeset -p " piped to a file looks like in 
geany:

However, I tried mcedit on the same file ... and it looks absolutely 
fine, so go figger.  Some charset or UTF or encoding or locale or who 
knows what.  Nevermind.
