I added the 3rd upload file.  I found the upload process does not allow files with .py extensions to be uploaded.  I change the name of the file by adding  .txt as the extension.

Dave,

Could you retry running the program 3 times but before you do enter the command 'REINIT.PYTHON OFF'

Jonathan Smith,
Thank you for your suggestion,  not sure where that command came from.

My results:   
       I tried your command "REINIT.PYTHON OFF" before running my test program, I received no more memory alloc errors....   It worked. I was all smiles. 

Sooooooo, I decided to test more.

Bottomline:
UniVerse 11.3.4 session will NOT unset the REINIT.PYTHON flag, even after running REINIT.PYTHON ON and checking REINIT.PYTHON STATUS (showed "ON").   I have to close the term window(session) and re-log in to get REINIT.PYTHON flag set back ON at session level.

Testing:
I tested by changing my python program to print some garbage.  It would not print the garbage.  I had to close my accuterm7 window and re-log  in the UniVerse TCL prompt.  Then I ran the python program and the garbage printed.   I set Reinit to OFF and back ON.  After doing that, I removed my garbage print statement from python(saved it), then ran the basic program which calls the python test program and I continued to get the garbage.  Reinit did not set back to ON.

I did one more test. 
I reloaded my TCL window and modified  my basic program, at the top I added EXECUTE "REINIT.PYTHON OFF" and at the bottom I added EXECUTE "REINIT.PYTHON ON" . I ran my test program 3 times and received the memory alloc error and crashed my session.  So running the commands with-in a basic program will not work.  Hey Rocket,  This would be a great addition.
We wrote a small basic program to just run
     EXECUTE "REINIT.PYTHON OFF" 
then run: 
    EXECUTE "REINIT.PYTHON STATUS"
then run
     EXECUTE "REINIT.PYTHON ON"
then run:
     EXECUTE "REINIT.PYTHON STATUS"

The output showed what we wanted to see    First status output showed OFF,  Second status output showed ON.

Dave,

The problem with  the 'REINIT.PYTHON ON' after issuing a 'REINIT.PYTHON OFF' is a known problem and will be fixed in a later release of both UniVerse (and UniData).  The reason why the verb was introduced is it each time python is invoked from UniVere or UniData the python environment itself is re-initalized. The problem that you saw with the re-initialization turned on is that depending on the coding techniques and assumptions made in the Python code being used, the implied re-initialization of the Python environment might not be supported when used for a second time in the same session.

Regards,
