Hi Alex,

Thanks for the reply and the details.

The Unlimited design of PicoLisp is incredibly powerful. To clarify, I was
seeking some guidance on a reasonable upper limit on variable length arrays
that doesn't significantly handicap the language for demoing in an
emscripten environment. The proper solution is likely to use malloc/free
but that would introduce additional effort/complexity that might be
unnecessary for a proof of concept. I sometimes prefer hacking a small
change just to see if it's possible before letting myself go down a rabbit

It sounds like the reasonable upper limit might depend on the function. I
think I may have changed approximately 8 places that use the sym/val
structure.  I'll take a closer look. I was hopeful that there might have
been a quick answer that will work the vast majority of use cases with
little or no impact on run time and memory.
