Can you try something like:

DECLARE INTEGER ShellExecute IN "shell32.dll";
   INTEGER hwnd,;
   STRING  @ lpOperation,;
   STRING  @ lpFile,;
   STRING  @ lpParameters,;
   STRING  @ lpDirectory,;
   INTEGER nShowCmd
ShellExecute( 0, "open", "c:\windows\notepad.exe", "c:\temp\test.txt", "", 1 )

>I have a customer using WIN NT and the RUN or ! command will not work. I even had him copy c:\winnt\system32\cmd.exe and command.com to his starting folder, but even a statement like
>!cmd.exe
>gets a file not found. Statements like
>!pkzip25.exe
>just flash a black screen. I had him check his starting folder and PKZIP25 is there! My system, using WIN98 and all my other customers do not have this problem. Any suggestions?
