The prompt appears when the parent finishes, even if the children haven't finished yet. If you want the parent to wait for all the children to finish, you can add a statement like the following at the end of your main program: 1 while wait != -1; wait() returns -1 when there are no more children. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
