To All,

I have been attempting to execute the following program within the
Python environment:

<snip>

However, when I would try to execute the following lines of source
code within a python script file:

import os

os.system(r"C:\myprogramfolder\run\Myprogram.exe 1 1 acc 0")

<snip>

I believe I may be missing something here that prevents the executable

file working within python from utilizing this (.dat). The printed
final error is the following:

ERROR opening inputs/io/control.dat

Does anyone know what that could be ??

Based on your description, it seems pretty obvious (and easy to confirm)
that Myprogram.exe needs to be run from its containing directory
("C:\myprogramfolder\run"). Try something like this...

import os
pwd = os.getcwd()
os.chdir('c:/myprogramfolder/run')
os.system("Myprogram.exe 1 1 acc 0")
os.chdir(pwd)

HTH,
Marty
