Hi Russ,
so it looks like*integral.py* was properly installed and is working.
What remains is to check if python itself man can be found and started.
The first this that I wouid check is the *)MORE* information directly after
*⌹.integral* has failed. GNU APL tries to first run *python3 *and, if that
faild, *python*. Unfortunately there exist many different ways how python
is installed (global /usr/bin/python, per user installation somewhere in the
user's home, virtual installation, etc.) which makes it almost
impossible for
GNU APL to figure how to start python. The same problem exists for python
packages like *sympy* that can also be installed globally, locally, or
in a virtual
environment. For that reason I have added quite a few*)MORE *messages in
*⌹.integral* that should help finding out what went wrong, and the messages
printed from *⌹.integral* should tell us how far it came.
BTW the echo command that I posted earlier spans several lines and inserts
the line feeds that you inserted into your echo command. I personally find
line by line input more readable than multiple \n in strings.
Please keep me posted.
Best Regards,
Jürgen

Exact same error message here but with "Python 3.14.2" on Fedora 43.

Keyboard settings (de, us, apl) to not affect the output.
On my iPad running Termius, connected to either server or laptop,
the apl
sessions reproduce the ]keyb layout, including the apl chars, within
Termius correctly!
