Re: Getting the jBase DP (data pointer) of the current session when using pure C
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
expose jBASE business rules to any language. If are you trying to build a
full wrapper for Python to allow you to code directly in Python vs Pick
Basic then you will need Peter. Keep in mind jBASE now offers direct
inline C inside Pick Code which allows the opposite where you can directly
call Python functions from jBASE by using the Python/C integration
examples.
Jim, from docker do
docker pull zumasys/jbase_base
docker run -it zumasys/jbase_base jb
Enjoy =)

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 possibility to retrieve and use the
current session DP somehow? So that no child session would get created
Any advice would be highly appreciated
Thanks in advance
PS: to the admin, it is actually a jBase related question rather than
TAFC. Thanks
Kind regards,
Igor

Re: 3.10 and Windows 10
We have recently updated our download page at Zumasys making it easier to get a developer/demo copy of jBase 5.7. We have also released a quick start video on how to get started on windows 10 with jBASE. https://www.youtube.com/watch?v=Z-K9YcDiGiU - Video https://www.zumasys.com/downloads - Downloads and eval/license request It shouldn't be too difficult to port your application from jBASE 3.2 to jBASE 5.7.1. jBASE 5.7.1 now supports using the Visual Studio as the compiler including the community edition.

Re: Issue with umask and openseq
Jose, OPENSEQ if it creates the file does not use umask but instead always does it with a mode 0666 which is the behavior you are seeing. Unfortunately there is no overriding mask option. You can although create the file first using the unix command touch which will create it according to your umask and then use OPENSEQ to open the file.

Re: Creating an index on a multi-part key
Hey Rick, I am wondering if it is getting confused. I like to create the index against the actual dictionary and see what jBase does automatically. In your case I made another dictionary in which attribute 8 is a;3:"*":4 <-- This should be faster than using the N features. Then I did a create-index sched.detail jBase created as such Notice: Command converted to 'CREATE-INDEX NW.ORDERS TEST.INDEX BY ICONV(0,\A;3:"*":4\)' I did a test select and it did use the index. With more complicated indexes such as this I prefer to do it off the dictionary as it makes jBase better guess that it has a index to use.
