Correct. But the message "not defined at this point" is
Euphoria's response (in the trace mode) to *any* reference
to an element of a sequence:
name = "Irv"
? name will print "Irv", whereas (in the debugger) ? name[1] will
say "not defined at this point".
What it really is saying is: Euphoria can't do that, even though
it can easily reference the same array elements programmatically.
Try this:

with trace
sequence array
array = repeat(repeat({},100),400)
trace(1)
array[371][41] = 49
? array[371][41]
-- look at array in the trace mode.

Other than sprinkling print statements thru the code, you can use
the type () function to track changes to an element of an array.
