I've already stated that it was my intention to pass an "object" (to simulate an array).

The object ("o1") is being passed into the script as "to1" via the lparamter statement.

"to1.a[1] = 'fee'" is a statement in the script.

(I could have placed the parameter statement and assign in a string and passed the string to EXECSCRIPT() ... same difference).

These is NO "external reference" in the script (which would have been "o1").

o1 can be public, local, or private ... no difference. Objects are ALWAYS passed by reference.
