OS.SYSTEM ERROR !!!

[Blubaugh, David A.]

To All, 


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

Myprogram.exe, which means this is an executable file!!

I would usually execute this program (with the appropriate arguments) by
going to following directory within MS-DOS (Windows XP):

C:\myprogramfolder\run> Myprogram.exe 1 1 acc 0


The executable would execute perfectly.  


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") 


The executable file would start to execute until it would print an error
stating that it cannot use a (.dat) file, which is located under the
following directory:  


C:\myprogramfolder\run\inputs\io\control.dat


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 ??


Thanks,


David Blubaugh
