   \item `\texttt{*}' is multiplication, `\texttt{**}' is exponentiation.

     This tells Fortran to print 4 records of integer type, each having a width of 6 characters (including spaces), per line. 
-    Format strings for other datatypes include \texttt{Ew.d} (real -- decimal form), \texttt{ESw.d} (real -- scientific form), \texttt{ENw.d} (real -- engineering form), \texttt{Lw} (logical), and \texttt{A} (characters). Here, \texttt{w} gives the width of a record and \texttt{d} gives the number of places right of the decimal.

 Note that \texttt{./} specifies the \emph{path}, \ie, the location where to find the program.
 The dot means the current directory (similarly, \texttt{..} refers to the parent directory), and the slash separates directories and file names (like the backslash in DOS and Windows).
