Clarification for Open Interface: Op-codes and Data Bytes

Many of the commands listed in the Open Interface document note the number of "data bytes" it requires.
For example, the drive commands say there are 4 data bytes, so they both require 4 more bytes after the op-code.
Keep in mind, however, that the op-code is also a byte. When you issue a drive command, you are sending 5 bytes
(1 op-code byte, 4 data bytes). Keep this in mind when you are using the script command.
