14 /* Notes:
15  * 1. The FETCH_A through FETCH_L and STORE_A through STORE_L opcodes must
16  * be contiguous.
17  * 2. The LITERAL opcodes are followed by a binary representation of their
18  * values, but these are not aligned properly.
19  * 3. The var-arg functions MIN, MAX, FINITE and ISNAN are followed by
20  * a byte giving the number of arguments to process.
21  * 4. You can't use strlen() on an RPN buffer since the literal values
22  * can contain zero bytes.
