Devon asked. > Are you sure it's due to cmd.exe? Yep. Open a command prompt and type cmd /C "C:\amisc\sound\music\Fifties & Sixties\renLen.bat" (i.e. prefix your line with cmd /C ) . That's the string that shell_jtask_ passes to Windows' CreateProcess API.
The reason you can run the line OK from the command prompt is exactly the same reason that calling spawn_jtask_ directly will work: cmd.exe's parsing doesn't intrude. It is shell_jtask_ that prefixes the line with cmd /C . The lower-level verb spawn_jtask_ does not. -Dan ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
