concerning either a bug or just plain difficulty isolating errors:
Near term recommendation, change or add examples to j documents. The
sample in jforc/error_messages.htm leaves me believing "immediately
before":
The interpreter removes any excess spaces from the
sentence and then adds three spaces before the word whose
execution triggered the error. For example:
2 3 + 0 1 2 * 3 4 5
|length error
| 2 3 +0 1 2*3 4 5
The error occurred during the execution of the + verb.
