[Jprogramming] Jupyter Versions of J Labs [for jod]

[David Mitchell]

I tried this on j807 on windows.

I had no errors, but the od output was the same as you reported.

I looked at the source for the Jod Introduction Lab and found this:

   {
    "cell_type": "code",
    "execution_count": 4,
    "metadata": {},
    "outputs": [
     {
      "name": "stdout",
      "output_type": "stream",
      "text": [
...
 
"│1│docs│imex│jod│joddev│lab│labdev│play│smugpyter│utils│\n",

So the output is hard coded in the Lab source.

I suspect that the dictionaries listed in the JSON Lab source represent the JOD 
environment present at the time the Jupyter Lab was generated.
