1. expression evaluation
Rob,
can I safely assume strict left-to-right expression evaluation (unless, of
course, mandated otherwise by the precedence of operators)?

Yes. That's the general rule, though I'd feel safer
if you would give a specific example.

Thanks, Robert. Is the following fragment specific enough?
object result
integer level
function foo(...)
...
level = ...
return ...
end function
...
result = foo(...) * level
In the last line: is foo() always evaluated first, so that level is
appropriately set?
