This approach works, i.e. if we use a JBC program to call a Python that
would call a C written extension module then DP is just passed and no
additional session is being created.
But would be great not to use JBC as a starting point

Thank you Peter
But do you think it is still possible to retrieve a DP for an existing
If you want to use python in this mix then I would think you need to call
python from jBASE so you can persist the dp.

Thank you Peter
But do you think it is still possible to retrieve a DP for an existing
session?
It can be seen that no new session is created when a JBC program is being
called in jshell e.g. Therefore a DP initialization is happening somehow
for that case
Thanks

Whichever method you use to get a dp, it is up to you to store it in a
persistent object.

That creates a regular jBASE session dp. The null args are more for internal
use.

Peter, we are using jBase 5.1
I've now tried to use
static DPSTRUCT *dp = jbase_getdp_nocreate(NULL,NULL,1,NULL);
but it still creates a new session...
Would that be possible maybe to give an example of how
jbase_getdp_nocreate() could be used please?
Its name sounds like intending not to
Marco, thank you for your shared experience
Regarding dp initialization the next was observed: if your starting point is
JBC code that will in turn call the C extension, then dp is really initialized
automatically. Whereas if you launch C/Python directly then dp is NULL and smth
has to be done
Peter, thanks for the code sample
Could you please elaborate on what exactly the next line means
jbase_getdpEX(NULL,NULL,1,NULL)
Thanks
Igor

Igor I see that you are trying to call into jBASE functions directly from
Python, correct? Based on what you are trying to do and required
performance jBASE does now offer a Rest Interface which allows you to

Hi,
On some earlier release of jBase 5, I once had a need to "divert" a jBC
subroutine call to go via my own jBC subroutine with the same name that
then called the original (for which I didn't have source). I remember
creating a C function to achieve that. The C function was declared like
below.
Haven't found my "working" example yet (might've been on a docker I blew
away). I did find some WIP code but some of the includes it uses are not
distributed.
Maybe this will help you get further until I find something concrete:
#include "Python.h"
#include
int ParseArguments(char*
What version of jBASE do you have?

Thanks Peter, would be really helpful!
I've tried two ways
1. ctypes library. I managed to call a JBC function but it requires quite a
lot work as the explicit variable types are required in this case. So all
the transformations from PythonObj to a C type is required for each
argument. Also in
We have some examples of python calling a subroutine and vice versa. I will dig
around.

I've simplified the code a bit in my previous reply to give an idea.
Actually dp is defined as a static variable in a separate class and its
value is returned by a dedicated class function.

Hello Jim,

Yes, that's the idea. Actually the final goal is wider, namely to write a
Python extension in C that would call JBC functions. Basically I managed to
do it but
Wow - it has been a long time since that code ;) However, what you ask is
possible I believe. It depends on your context. Are writing a pure C
program and wish to call in to subroutines etc?
Probably the best place to start is to generate the C code for a very small
jBC program:
lufc.b
CRT
Can you post some code?

Dear all
I need the jBase DP (data pointer) to be initialized. I've actually managed
to initialize it by calling the jbase_getdp(). But in both cases the new
child session is created in jshell (and gets removed automatically after
the code has been executed).
So I am wondering: is there a
