Yes, I will try that tomorrow. Thanks.

I haven't changed anything in the Lua code. I don't know about
"compiling with nonstandard options"; could you explain further?

I don't believe there are any DLLs involved. I built lua.exe from all
the source files that make it up. The script loads a number of files
via both 'require" and direct loading.

However, none of those change between runs of the same data.

Not intentionally.
