I didn't realize strings were special in this sense -- 
are there other special kinds of arrays with limits smaller than
the general case?
 
So one possibility would be to store something other than characters
in the arrays, like char-codes of the characters.

So TYPECODES must be false.  
If it were true then the limit would be 16x higher.
I gather TYPECODES is controlled by some build options?  
Impnotes seems to say there are several different ways to 
get different combinations including typecodes, but I can't
tell from that which build options are available for this
platform and what other negative (or positive) consequences
would result from each.

What's the difference between ampere and intel that leads to this
difference?
on Ampere

not so convenient for adjustable arrays
I'm looking for alternatives to that approach.
Using a different machine seems to be another possibility.
