 4 Printing Output
 *****************
 
 One of the most common programming actions is to "print", or output,
 some or all of the input.  Use the `print' statement for simple output,
 and the `printf' statement for fancier formatting.  The `print'
 statement is not limited when computing _which_ values to print.
 However, with two exceptions, you cannot specify _how_ to print
 them--how many columns, whether to use exponential notation or not, and
 so on.  (For the exceptions,  Output Separators, and 
 OFMT.)  For printing with specifications, you need the `printf'
 statement ( Printf).
 
    Besides basic and formatted printing, this major node also covers
 I/O redirections to files and pipes, introduces the special file names
 that `gawk' processes internally, and discusses the `close' built-in
 function.
