The value of J is being passed to the CP stage as an input record.  Most
of the values aren't valid command names and so don't give any output.
When you get to BA, BE, and EC, those are valid abbreviations of
BACKSPACE, BEGIN (also no output), and ECHO.  You're lucky there isn't
anything more destructive abbreviated by two hex digits!

Also, did you notice that your queries start with an invalid one and only
run to FE, not FF?  Pipelines can't do time travel.  You're building the
Q CHPID command from the value of J *before* your pipeline is issued.
Instead, you could use SPECS to build the command from the current value
of I, and pass it to the CP stage as an input record.  Assuming you don't
need the value of J for anything else:

  'PIPE var i | specs "Q CHPID " 1 1-* d2x next | cp | console'

And if you also don't need I for anything else, you can replace the whole
loop with one pipeline:

 'PIPE literal | dup 255 | specs "Q CHPID " 1 number from 0 d2x next | cp
  | console'
