David, I will have to complain that your python benchmark is not a fair
comparison. Your python script uses a module named pyzfile to access z/OS
files (which I see from PYPI is authored by you but for which you have
published no source yet). A fairer comparison would be a python script that

While I understand that it may be an unpopular opinion on this forum, I
personally believe that the ISPF editor is outdated relic. As Peter
mentioned, VS Code is a fantastic alternative. Additionally, Microsoft's
GitHub offers the Copilot plugin, which functions as an AI programming
assistant.
