[Octave-bug-tracker] [bug #31080] User scripts or functions created during a session on Windows are not found

[Dennis Cote]

Follow-up Comment #75, bug #31080 (group octave):

I continued testing with Octave 9.3.0 installed by the Windows release
installer at https://octave.org/download. 

If I create a new *.m file and save it to a path that is not already in the
Octave path() list then its path is not added to the octave path list and
trying to execute the file in the command window produces the undefined error.


I dumped the path() list before creating the new file and again after saving
the file. The file's path (using the Editor by right-clicking the file's tab
heading and selecting Copy Full File Path) is
C:/Users/DennisC/Octave_Files/testing/test_add_vec_3.m. The path list after
saving the file is:

>> ps = transpose(strsplit(path(), ";"))
ps =

Which does not contain the path to the newly created and saved file which is
in C:/Users/DennisC/Octave_Files/testing/

Trying to execute the new script file produces the undefined error:

>> test_add_vec_3
error: 'test_add_vec_3' undefined near line 1, column 1
