So, how the frell do you use this?  Well, that's hard to say.  There doesn't seem to be a recognizable targeting variable, but you may be able to use it in conjunction with the [1C 10 ] and [0B ] character targeting codes.  I do know that if you have an item that displays text and you put this in, only the person who uses it is affected.  Here's a bit of code from JonBound: Dark Future as an example:

@[1C 0D] used the Spam![03 00]  The smell was intensely nauseating![03 00]@[1C 0D] felt sick.
[0E 01 0D 01 1B 04 1B 00 1B 01 19 05 00 01 05 13 02]

If somebody, say, Jeff, for example, used that item, this will appear in the game as:
•Jeff used the Spam!
  The smell was intensely nauseating!
•Jeff felt sick.

At this point, Jeff begins dripping with sweat and his HP starts dropping.  If you don't have a specific person as a user target, then it affects the first available living person in your party like the Give Item code.
