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

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!!
Cheers,
