I am trying to use Python to communicate and send commands in MSC Marc. A part
of the code looks something like this:
from py_mentat import*
directory = '[specified the file path to my model]'
marcModel = '[name of my model]'
py_echo(0)
openModel = '*new_model yes *open_model "'+ directory + marcModel +'"'
py_send(openModel)
The code stops at "py_send(openModel)" with an error message that reads: Traceback (most
recent call last): File "[my file path]", line 11, in py_send(openModel)
SystemError: error return without exception set
I tried running the code on different platforms (e.g. Command Prompt, Wing 101,
python.exe) and I get the same result. What could be the problem?
It looks like it's calling some code written in C that's returning NULL,
which indicates there's an error.
The code should've set the exception that should be raised, but it
hasn't done that.
That's a bug in the C code.
