I wasn't sure if I needed that for my initialisation - you answered my question

Ah ha! That explains the crash that happens when it gets errors :-)

Yes it does have that issue.   What I want is to get similar eval/print 
behavior that we get from:

   while (!feof(stdin))
      load(NULL, ':', Nil);

in main(), except I'd like to be able to hand it a s-expression in a string 
like "(+ 1 1)" for evaluation, leaving the I/O unaffected.  

I was hoping I could do this leaving Env.get/.put untouched. 

But due to the character-oriented way LISPs most often parse things, it is 
looking now like I really will indeed need to make  Env.get (at least) read 
from a character buffer.  (And then doEval(doRead()) in place of the load() I 
am using now.)

My goal is to be able to easily embed (mini)picolisp (and pilog) in C/C++ 
projects like people now embed lua in applications when they want to add 
scripting.  :-)

Thanks for the guidance!!
