Thanks to everybody for your help.

I found the response looking in google and Borland newsgroups. Is very stupid and is simply put /C after Command.Com like:

Command.com /C Dir C:\

With this switch the dos box dialog dissapear after execution. With command /? you get other options.

But this is not enough, is necessary look for the comspec OS variable before run this because the command.com can be replace with cmd.exe or other.


Thanks
