how to keep "System Exec" section open

[atd]

Hi,

I use "System Exec" to launch a Python script.  The script launched successfully, however, the System Exec also ended.  There are many environment settings done by this Python script so I want to keep the section open for subsequence Python scripts/commands.  Could this be done with "System Exec"?  If not, what is the easy way to do this.  Some example would be great.

thanks,

Hi Anh,

it should stay opened if you connect a false constant to the "wait for end of operation" input on top of the vi.

Another possibility could be to load your script from a batch file with a "pause" command at the end.

Hi Mike,

I tried that "wait until completion -> False" already.  It will keep the actual "cmd window" open, but not the Labview section.  What I want to do is to run the initial Python setup script, keep this Python section open, then at random times later, my LV program will send more Python commands/scripts to the same opened-section.  

thanks,

Have you tried LabPython?
