How can I start an executable program and send its parameters?  
And I need to prevent the black DOS box.

I tried @Shell but that gives me the DOS box that is unwanted.
I tried @AsynchShell, but that does not send the parameters.

The following command line with three variables works good from a DOS prompt:
Volume.exe /15 /1800 /30

But when I use @AsynchShell I get a message that it cannot find the file "Volume.exe /15 /1800 /30"

I have tried the following, but they fail.
n = @AsynchShell("C:\Program Files\CADD\Volume.exe /15 /1800 /30")
n = @AsynchShell("C:\Program Files\CADD\Volume.exe" + " /15 /1800 /30")

This starts the program OK without the parameters:
n = @AsynchShell("C:\Program Files\CADD\Volume.exe")

It is intended to have the three variables passed over from variables calculated by Sesame.  But I can't even get it to work with hardcoded values first.  I tried putting the command line above into a batch file and call the batch file with @AsynchShell but I get the black DOS box then.  IS there a way to make the black box disappear when the batch file runs?  It could run minimized, because the result from the executable will be written to a text file.  I will be using Sesame to read the text file result after running the executable.

Although this is a specific question, I think that it is of general need for any other programs that need variables passed to them.  What is the secret?
