for some reason in VBScript it works fine.
What makes it different, with Python?
I tried all possible ways to combine quotes, ' and ",
with no avail

I think your problem lies with your "\n", escape chars. Assuming these
are not arguments and are indeed separating statements, I suggest
replacing "\n", with "&". That way, the command shell probably wont

An example:
ml = 'line1 & line2 & line3'

My crystall ball says you want

subprocess.call (["some.exe", ml])

exec is a python statement that executes python code.

actually, it's this doesn't work (again, in VBS the "same"
construction works properly):

f = os.popen('osql -E -S(local) -dpubs -w800 -Q"' + query + '"', 'r')

res=f.readlines ()

here "query" is a multiline string like:

select getdate()

select 555*666

select getdate()

No, it would be too easy & simple. While stdin is NOT CLOSED stdout has not EOF, but readlines() waits for its appearence ... and so freezes for good. IMO. Should be like this: import popen2 o=popen2.popen2('osql -E -S(local) -dpubs -c"GO" -n -w8000') while 1: o.write(raw_input()+'\nGO\n') o.flush() # this line can be commented
