gprintf

A gprintf is a I/O operation for printing a ``global'' String value. All they do is output string to System.out on the root process of the active process group. They have interfaces:

$$\begin{minipage}[t]{\linewidth}\small\begin{tabbing} \verb$ gpri... ... \verb$$\\ \verb$ gprintln(String string)$\\ \end{tabbing} \end{minipage}$$

The interface gprintf() is equivalent to System.out.print() and the interface gprintln() is eqivalent to System.out.println().
