I apologize, but I still cannot get my script loaded from Python.
Making the connection:
cdll.LoadLibrary("j801/bin/libj.so")
j = CDLL("j801/bin/libj.so")
p=j.JInit()
run_jcmd("load 'j801/bin/profile.ijs' ") #file exists in this location
run_jcmd("load 'j801-user/temp/myscript.ijs' ") #file exists
None of the public verbs from my script are callable, rying to call a verb
after loading the script and then trying to get the result gives a None
response, in python, indicating nothing was returned.
I am also unsure specifically in the J manual where I am supposed to be
looking. I've read through a few different pages but cannot find what it is I
am missing.
If anyone can point me in the right direction, I'd be very grateful.
