You may want to modify the environment variable by modifying the
os.environ dictionary before the os.system() call.

E.g.

os.environ['CATI'] = '199904'

I don't understand why you think that line 14 has anything to do with
environment variables, though -- line 12 does.  So I'd put the
line above before line 12 and that might do the job.
