Newbie Question on osCall Windows 7

Newbie to SmallTalk (using 7.5), so please be gentle!

Say I am running a program out of Smalltalk called "myprog.exe". I am using the code below and it works well.

(OSCall new) createProcess: nil
lpszCommandLine: 'c:\myfolder\myprog.exe'
lpsaProcess: 0
lpsaThread: 0
fInheritHandles: false
fdwCreate: 0
lpvEnvironment: 0
lpszCurDir: 'c:\myfolder\'
lpsiStartInfo: (OSStartupinfo new)
lppiProcInfo: (OSProcessInformation new).

However, it looks like it is creating a new instance of OS and the environment variables are being defaulted.

Is there a way to [re]set an environment variable for use by "myprog.exe"?

Thanks in advance.

I would guess, that lpvEnvironment is a good way to achieve, what you want to do ... actually I have not done this by myself yet
