Access Violation in function CreateProcess in Delphi 2009

In my program I've the following code:

//Code
 if not CreateProcess(nil, NonConstCmd, nil, nil, True, NORMAL_PRIORITY_CLASS or
    CREATE_NEW_PROCESS_GROUP, nil, PCh, SI, P) then
//Code

And I keep getting Access violation error. By the way, in Delphi7 the same code works perfectly. I've read MSDN and found that CreateProcess function in Delphi can modify the second argument. Inititally It was const, that's why I create a new variable with the same value. But it takes no effect.

The question is: why doesn't this code work?
