Hi

Use could use the shellexecute api, here is a sample snippet of code

Declare INTEGER FindWindow IN "user32" String strClassName, INTEGER lpWindowName
Declare INTEGER ShellExecute IN "Shell32" Integer hWnd , String lpszOp ,String lpszFile ,String lpszParams , String lpszDir ,Integer fsShowCmd



? ShellExecute(0, "Open", "c:\MY DOCUMENTS\PKZIP.EXE", "", "", 0)
wait wind "no show"

? ShellExecute(0, "Open", "c:\MY DOCUMENTS\PKZIP.EXE", "", "", 1)
wait wind "normal"
? ShellExecute(0, "Open", "c:\MY DOCUMENTS\PKZIP.EXE", "", "", 2)
wait wind "minimised"
? ShellExecute(0, "Open", "c:\MY DOCUMENTS\PKZIP.EXE", "", "", 3)
wait wind "maximised"
?FindWindow("tty",1)
?FindWindow("tty",0)

hope this helps
