Heavy duty suggestions.  The difference between your level and my 
level.  If it wasn't presumptuous I'd just ask you to clean it up for me 
and then I'd study the changes.  Otherwise I'll see if I can understand 
and implement.  I know my code is amateurish.   Ah, for a master class, 
where I could have all my code critiqued.

Can't argue with that.  OTOH most people conform their expectations to 
what's currently available -- basically they only ask for what they 
have.  But if better information were available, they might very well 
come to value and expect that.  Not to wander too far off topic but 
Windows users think that Windows is 'the universe' and that there's 
nothing more or better to even be contemplated.  And when you tell them 
that there is more and better, they aren't even interested cuz it would 
involve expanding their tiny minds.

1 /aWorking/Zsh/Source/Wk 1 $ v path

Stes  PATH = 
.:/aWorking/Zsh/System:/aWorking/Bin:/usr/local/bin:/usr/sbin:/usr/bin

Ats   path = ( . /aWorking/Zsh/System /aWorking/Bin /usr/local/bin 
/usr/sbin /usr/bin ) ...

... because the above is accurate.  If that information had been 
(easily) available to me, this thread would never have been started.   
What is a tied variable?  As we see, a scalar is created from an array, 
named in all caps, and then exported.  As it was:


0 /aWorking/Zsh/Source/Wk 0 $ typeset -p PATH
export -T PATH path=( . /aWorking/Zsh/System /aWorking/Bin 
/usr/local/bin /usr/sbin /usr/bin )

... and I'm interpreting that as saying that PATH and path are two 
different names for the same var.  It seems like so long ago :(

The expanded 'full-word' descriptions are of course available, but with 
the compressed form one has room for the value too.  Once I sort out 
your suggestions above I think I'll add a 'full word' switch, but 
without the values.  Mind I already have that with:


0 /aWorking/Zsh/Source/Wk 0 $ allvars

ALL VARIABLES AND THEIR TYPES:

$                         integer-readonly-special
0                         scalar-special
aa                        scalar
a                         integer
aliases                   undefined
ARGC                      integer-readonly-special

...

zsh_eval_context          array-readonly-tied-special
ZSH_EVAL_CONTEXT          scalar-readonly-tied-special
ZSH_NAME                  scalar
ZSH_PATCHLEVEL            scalar
zsh_scheduled_events      undefined
ZSH_SUBSHELL              integer-readonly-special
ZSH_VERSION               scalar

... work in progress of course.
