[Jprogramming] Request for 15!:x: address of data

[Henry Rich]

Interesting.  I looked in jmf, and I tried

15!:7 verb

which crashed J.

I can't see which of these tells me the address of the data for a noun. 
  Can you help?

I can't make any sense of the description of 15!:6 so I didn't try it.
