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, Note: Output Separators, and Note: Controlling Numeric Output with `print'.) For that, you need the `printf' statement (Note: Using `printf' Statements for Fancier Printing.). 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.
