Running DOS Commands parallely

Hi,

I have 3 MS-DOS commands, which I want to run in parallel.
I approached like this:
Created a sequence.
Added 3 Command Stages to it and ran the commands.
The commands were triggerred in parallel as desired.

Due, to some reasons, I need to run the same commands from
a routine, so I approached like this:
Created a rotuine, which takes in the command ( with params ) as
the input arg, which calls DSExecute() to run the command.

Now, I created a new sequence.
Added 3 routine activity stages to it, passing the different commands as different parameters to the same routine.
But now, the 3 commands are not running in parallel now.
i.e the routine is not triggering parallely to run the 3 different input commands as desired.

Please explain.

Thanks and Regards.

Do you mean to say, one wait till the other one finishes?

yes, the one DOS command is waiting for the previous one to finish.

On Unix you can stick a '&' in between the commands to fire them simultaneously. Try that on DOS.

Yah, go ahead - I dares ya.

hey am sorry to change my reply..

still the sequence of execution depends on the sequence of commands separated by '&'.

My target is to break this sequence.

How about three Execute Command activities in a job sequence, with NO LINKS between them?
